Liposomes for drug delivery - liposomes

Liposomes are a novel drug delivery system (NDDS), they are vesicular structures consisting of bilalyers which form spontaneously when phospholipids are dispersed in water. They are microscopic vesicles in which an aqueous volume is entirely enclosed by a membrane composed of lipid bilayers. NDDS aims to deliver the drug at a rate directed by the needs of the body during the period of treatment and direct the place of action. Liposomes are colloidal spheres of cholesterol non-toxic surfactants, sphingolipids, glycolipids, long chain fatty acids and even membrane proteins and drug molecules or it is also called vesicular system. It differs in size, composition and charge and drug carrier loaded with variety of molecules such as small drug molecules, proteins, nucleotides or plasmids etc. Few drugs are formulated as liposomes to improve their therapeutic index. Hence a number of vesicular drug delivery systems such as liposomes, niosomes, transfersomes and pharmacosomes are developed. The focus of this chapter is to the various method of preparation, characterization of liposomes, advantages and applications, etc. Liposomes for Drug Delivery - liposomes

A lightweight deep learning framework using resource-efficient batch normalization for sarcasm detection

Communication is not always direct; it often involves nuanced elements like humor, irony, and sarcasm. This study introduces a novel two-level approach for sarcasm detection, leveraging Convolutional Neural Networks (CNNs). Convolutional neural networks (CNNs) are crucial for many deep learning applications, yet their deployment on IoT devices is challenged by resource constraints and the need for low latency, particularly in on-device training. Traditional methods of deploying large CNN models on these devices often lead to suboptimal performance and increased energy consumption. To address this, our paper proposes an energy-efficient CNN design by optimising batch normalisation operations. Batch normalisation is vital for deep learning, aiding in faster convergence and stabilising gradient flow, but there has been limited research on creating energy-efficient and lightweight CNNs with optimised batch normalisation. This study proposes a 3R (reduce, reuse, recycle) optimisation technique for batch normalization. This technique introduces an energy-efficient CNN architecture. We investigate the use of batch normalization optimization to streamline memory usage and computational complexity, aiming to uphold or improve model performance on CPU-based systems. Additionally, we evaluate its effectiveness across diverse datasets, focusing on energy efficiency and adaptability in different settings. Furthermore, we analyze how batch normalization influences the performance and effectiveness of activation functions and pooling layers in neural network designs. Our results highlight batch normalization's ability to enhance computational efficiency, particularly on devices with limited resources.

Prescribing patterns in systemic hypertension and pharmaco-economics (cost effectiveness and cost minimisation analyses) of the commonly prescribed antihypertensives in a district hospital in enugu state, southeast nigeria

Background: Prescribing patterns in systemic hypertension vary from place to place. Studies have shown that cost could be one of the factors responsible for non-adherence to treatment among hypertensive patients. Nigerian pharmacoeconomics studies have not provided a general guide on cost-effective prescribing for hypertensive patients in the country. The aim of the study was to examine the prescribing patterns, do cost effectiveness and cost minimisation analyses of the commonly prescribed antihypertensives, and determine if cost is a major reason many of the hypertensive patients of the District Hospital are usually lost to follow up. Methods: 5267 adult (≥18 years) non-antenatal patients’ cards of 2016 were reviewed for hypertension. Examination of the prescriptions, cost-effectiveness and cost-minimisation analyses of the commonly prescribed antihypertensives were done. Results: 12.6% of the patients were hypertensive. 73% of these hypertensive patients were treated pharmacologically. 40.8% adhered to treatment. 73% of the adherent ones responded to treatment. Amlodipine was the most expensive prescribed antihypertensive (N22). Amiloride-hydrochlorothiazide with the largest cost effectiveness ratio (CER) (9) was the most cost effective of all the combinations. Lisinopril- hydrochlorothiazide (N17) was preferable to the triple combination of lisinopril-amlodipine-hydrochlorothiazide (N39), and amlodipine-hydrochlorothiazide (N32) in cost minimisation. Conclusions: Cost of drugs probably had played a significant role in non-adherence to treatment among hypertensive patients in the District Hospital in 2016, since moduretic with the largest CER (9) and nifedipine with the greatest BP reduction when combined with hydrochlorothiazide (56/22 mm Hg) were rarely prescribed.

Employment status of persons living with mental illness in india: ground reality

The main aim of rehabilitation is vocational independence and community integration. Rehabilitation is complete with the person being a productive member within the community. But this is quite a challenging task as can be vouched by any of the professionals working in this field. What are the barriers and facilitators towards employment or return to work in case of persons living with mental illness? Literature shows that multiple factors are governing the ability to take up gainful employment. Most of this literature is about the western world where the social fabric is more supportive of individual autonomy. India lags in its rehabilitation efforts for mental illness. There is still stigma and lack of awareness about mental illnesses. This increases the problem of unemployment within persons living with mental illness manifold. There are very few detailed investigations into the vocational status of persons with mental illness and almost negligent literature existing in the Indian context. Hence, the current review article tries to examine the factors prevailing in the Indian scenario that influences the employment status.

In-silico drug design, synthesis, characterization and biological evaluation of 2-azetidinone derivatives for antileukemic activity

2-Azetidinone shows biological activities like anti-bacterial, anti-microbial activity, anti-tubercular activity, and anti-cancer activity. 2-azetdinone derivatives were synthesized by simple procedures. The first step is synthesis of benzohydrazide through nucleophilic substitution reaction between methyl benzoate and hydrazine hydrate. The above formed compound is then treated with substituted aromatic aldehydes in the presence of catalytic amount of concentrated hydrochloric acid with stirring for one hour to give benzohydrazone which results in the formation of Schiff bases.Schiff bases undergone cyclisation in the presence of chloroacetylchloride and diethylenediamine by using ethanol as a solvent upon stirring for 4 hour’s yielded 2-azetidinone derivatives. The in-silico anti-leukemic activity was determined by using the computational tools i.e. “PASS Online”, “AutoDock4.2” and “ADMET” properties by online software’s. Among these six derivatives compounds (AZT-6) was shown more activity when compared with the other five compounds.

The russian crisis communication response beyond mh17 tragedy

Effective crisis communication response through using the proper strategies is critical to cope with crises and to protect the reputation and existence of the involved parties. Usually, aviation accidents receive great attention from the media and the public. Malaysia Airlines Flight 17 (MH17) which was shot down over eastern Ukraine on 17 July 2014 during its scheduled flight from Amsterdam to Kuala Lumpur received global attention. This attention was due to the involvement of several countries either at the level of the countries of victims or the countries accused of the attack. Image repair theory proposed by William Benoit, the widely used in crisis communication response was implemented in this study. The Russian response to the international accusation, especially from the Western world on supporting the attackers of MH17 has been examined in this study. This study implemented both quantitative and qualitative content analysis to achieve its aims. A total of 306 news stories from the online New Straits Times newspaper Website from the years 2014 to 2019 were analysed. A total of 191 strategies were included in 123 news stories since some stories combined more than a strategy. Out of 191 strategies, 43.5% were simple denial, followed by shift the blame and attack accuser with 35.1% and 21.5% respectively.

Declining clinical skills in medical education: a perspective on its causes and potential solutions0

Medical science has grown tremendously at a rapid rate over the recent past. This is especially true in the fields of diagnostics and therapeutics encompassing various diseases of all the systems of the human body including psychosomatic disorders. During the past three to four decades, precision in diagnostics has enormously improved due to invention of multiple imaging modalities such as computerized tomography (CT) scan, magnetic resonance imaging (MRI) scan, positron emission tomography scan, ultrasound scanguided studies, CT-guided diagnostic procedures, Doppler studies, arteriography, CT angiography, advanced needle biopsy procedures, histochemistry studies, tumor marker studies, as well as in the ongoing improvements in all diagnostic and therapeutic branches. The surgical advancements due to increasing use of key-hole surgery using scopes such as arthroscope, laparoscope, colonoscope, and bronchoscope have revolutionized the surgical treatments and made surgery safer, less time-consuming, less costly, and less risky with reduced post-operative morbidity. Cardiac catheterization, percutaneous cardiac angiography, angioplasty, and vascular surgery have made the procedures/ surgeries related to the heart and major vessels, much simpler, faster, and safer minimizing the need for big infrastructures or large operative teams.

Role of human liver microsomes in in vitro metabolism of metamizole

Metamizole or Novalgin® is a widely used well tolerated analgesic drug which is however compromised by agranulocytosis as adverse effect. Subsequent to nonenzymatic hydrolysis, the primary metabolic step is N-demethylation of 4-methylaminoantipyrine (4-MAA) to 4-aminoantipyrine (4-AA). The aim of the present study was to identify the human cytochrome P-450 enzyme (CYP) mediating this reaction. This study identified the relevant CYP using virus expressed isolated human CYP, human liver microsomes and rat liver microsomes with chemical inhibition studies. The substrate of 4-methylaminantipyrine was employed at six different concentrations (25, 50, 100, 400, 800 and 1200 µmol per l) with varying concentrations of selective inhibitors of CYP1A2 (furafylline, fluvoxamine), CYP3A4 (ketoconazole), CYP2A6 (coumarin), CYP2D6 (quinidine), CYP2C19 (omeprazole, fluvoxamine, tranylcypromine), CYP2C9 (sulphaphenazole) and CYP1A1 (alpha-naphthoflavone). 4-MAA and 4-AA were analyzed by HPLC and enzyme kinetic parameters (Km and Vmax) were determined by regression (Sigma plot 9.0). The N-demethylation of 4-MAA by microsomes prepared from baculovirus expressing human CYP was pronounced with CYP2C19. Intrinsic clearance of the most active enzymes were 0.092, 0.027 and 0.026 for the CYP enzymes 2C19, 2D6 and 1A2, respectively. Metabolism by human liver microsomes was strongly inhibited by fluvoxamin, omeprazole and tranylcypromine (IC50 of 0.07, 0.07 and 0.18, respectively) but with coumarin, sulphaphenazole, ketoconazole, moclobemid, quinidine alpha-naphthoflavone and furafylline were 0.79, 1.20, 1.36, 1.44, 3.46, 4.68 and 8.41, respectively. The enzyme CYP2C19 apparently has an important role in N-demethylation of 4-methylaminoantipyrine which should be further analyzed in clinical studies and which may also be interesting concerning the agranulocytosis.

The silent scream of skin cells: a brief review of slow electrical signaling in the epithelium

Epithelial cells, lining the skin and internal organs, play a crucial role as protective barriers and regulators of substance transport. Traditionally, these cells were not considered to employ electrical signaling for communication. However, recent investigations have unveiled that epithelial cells generate slow electrical signals, termed the "silent scream," in response to injury, thus challenging conventional views of intercellular communication. A recent experimental investigation provided compelling evidence for this phenomenon, demonstrating the ability of these cells to transmit electrical signals over considerable distances within the epithelium. The research utilized microelectrode array chips to precisely detect subtle electrical events in keratinocytes and Madin-Darby Canine Kidney (MDCK) cells, revealing spiking activity characterized by slow propagation speeds, distinct from the rapid action potentials of neurons. The mechanisms underlying this novel signaling are explored, focusing on the involvement of mechanosensitive ion channels, calcium signaling, and Adenosine triphosphate (ATP) release. Calcium ions, well-established intracellular messengers, appear to play a central role in this biological phenomenon. Integrating this newly discovered communication mode into the existing understanding of skin cell biology reveals a more intricate picture of how skin senses and responds to its environment. The implications of this finding extend to various facets of skin physiology and pathology, including wound healing, inflammation, and skin aging. In wound healing, where endogenous electric fields guide cell migration and promote repair, this unique type of electrical signaling potentially plays a crucial part. Furthermore, aberrant electrical signaling might contribute to chronic inflammatory conditions, and age-related changes in this signaling could underlie the functional decline observed in aged skin. The potential for other environmental stressors to trigger the epithelial-generated electric signals also warrants investigation. The exploration concludes by discussing potential technological applications, such as bioelectric sensors and enhanced wound healing therapies, and future research directions aimed at further elucidating the molecular mechanisms and functional roles of this non-excitable cell electrophysiology.

Therapeutic potentials of crocin in medication of neurological disorders

Neurological sicknesses are severe, multifactorial, debilitating disorders that may cause neurodegeneration. Neuroprotection protects the structure and capacity of neurons from affronts emerging from cell injuries instigated by an assortment of specialists or neurodegenerative diseases. Various neurodegenerative diseases, including Alzheimer's, Parkinson's, and epilepsy, afflict many people worldwide, with increasing age representing the leading risk factor. Crocin is a natural carotenoid compound with therapeutic potential in managing neurological disease. In this review, we focused on the therapeutic capabilities of Crocin as a neuroprotective agent. The general neuroprotective impact and the various conceivable essential components identified with Crocin have been examined. In light of the substantial proof indicating the neuro-pharmacological viability of Crocin to different exploratory standards, it is concluded that Crocin exerts direct antioxidant, antiapoptotic and anti-inflammatory activities by multiple signalling pathways. Besides, Crocin was found to elevate dopamine levels in the brain during the experimental model of Parkinson's disease. Thus, this compound has been demonstrated to be a promising option for treating neurodegenerative diseases with few adverse effects. It should be further considered as a potential contender for neuro-therapeutics, concentrating on the mechanistic and clinical evidence for its effects.

The impact of juveniles' ages and levels of psychosocial maturity on judges' opinions about adjudicative competence

Determinations of competency in adult criminal court have an extensive history, both procedurally and conceptually. Unlike criminal court, however, juvenile courts were designed for rehabilitation, rather than punishment, and, historically, the issue of competency was not often raised. Recently, however, as stakes for youth in juvenile court have begun to parallel those of defendants in criminal court, youths’ competence has become an important issue. The purpose of this study was to investigate whether defendants’ age and maturity affect judges’ ratings of juveniles’ adjudicative competence in juvenile and criminal court. Three hundred forty two criminal and juvenile court judges reviewed one forensic psychological report about a hypothetical defendant; only the age (12-17) and maturity level (less mature; more mature) of the defendant varied across reports. The judges then rated the juvenile’s adjudicative competence in both juvenile and criminal court, provided ratings of the individual competence components, rated their confidence in their decision, and rated the importance of various characteristics of the juvenile to their decisions. Judges also provided demographic information. Results revealed a main effect for age, with older juveniles generally deemed more competent, and a main effect for maturity, with more mature juveniles generally deemed more competent. There was no interaction between age and maturity. Results suggest that age and maturity play major roles in judicial determinations of juvenile competency

A comprehensive analysis of behavioral patterns, socioeconomic conditions, and the prevalence of diabetes associated comorbidities among diabetic patients in bangladesh

Introduction: In Bangladesh, diabetes mellitus (DM) is a significant health concern contributing to numerous complications that enhance the mortality risk. This study aims to examine the impact of lifestyle patterns, socioeconomic conditions, and comorbidities among diabetic patients to establish valid associations between variables. Methods: A cross-sectional study was carried out among 450 patients with diabetes mellitus at the outpatient department of different hospitals in Bangladesh. Data collection was done through face-to-face interviews using a structured questionnaire. Results: The study analyzed sociodemographic and lifestyle traits among diabetic patients, categorized by gender and results were based on unadjusted analysis. Men had a higher prevalence of being married (99.4%) compared to women (97.9%). Women were more common in rural areas (67.5%) and less likely to own smartphones (12.3%, vs 24.7% for men). More women were overweight (31.2%) and owned house (92.1%). Clinical symptoms showed no significant gender associations except for headaches, more prevalent in women (OR=0.65; p=0.034). Women had a higher prevalence of cardiovascular disease (48.3%, vs 35.4% for men, OR=0.59; p=0.009), while kidney dysfunction was more prevalent in men (16.5%, vs 9.6% for women, OR=1.86; p=0.032). Allergic problems (20.5%, OR=0.40; p=0.014) and asthma (5.5%, OR=0.22; p=0.029) were more common in women. No association was observed in the occurrence of ulcer with the respondents’ gender. Regarding lifestyle, 50.7% of respondents consumed rice more than once daily, 71.8% did not smoke, and most (59.1%) had a normal BMI. Conclusions: Based on our study findings, men should focus on renal health by refraining from high-glycemic meals, while women should concentrate on managing their weight and cardiovascular health by utilizing modern healthcare facilities.

Intersection of caste and gender based subjugation

One of the unique features of Indian society is prevalence of caste system which was originated thousands of years back to demarcate the people engaged in different occupation or jobs. Initially it was not much rigid but gradually people belonging to upper castes for their own selfish means to maintain their monopoly made this arrangement hereditary and started treating people of lower castes disgracefully. For preservation of this system, people started controlling their women to prevent inter-caste marriages and the concept of endogamy came up. This robbed away many types of freedom from women. For women belonging to lower castes, this situation is worse as they are doubly subjugated on the basis on caste as well as gender. Men belonging to their own caste treat them as secondary beings. This paper throws light on this intersection. How intersection of these two kinds of inequalities place them at the lowest position in Indian society. Dr. B.R. Ambedkar rises as their leader who all his life worked for empowerment of downtrodden section of society. He argues that education is the primary tool for evading these differences among people. He further emphasizes to adopt the concept of exogamy to break the backbone of Indian caste system and to immediately leave a religion or culture which legitimizes such system of inequality among people of the same land.
