Studies on reproductive organs and morpho-anatomical features of leaf and stem in three traits of vinca rosea l.

Periwinkle or Vinca rosea L. has medicinal importance with three phenotypes i.e., Pink, Red eye and White. The present investigation distinguishes the three traits i.e., white, pink and red-eyed flower-bearing traits of V. rosea based on morphology, palynology, pollen grain germination and study of anatomical features of leaf, stem and variations in parts of the flower. The results revealed that significant differences were recorded in stomatal frequency, stomatal index, size of the petals, pollen viability and pollen germination. The highest per cent viability appears in pink flower-bearing plants (98.8%) followed by red-eyed flower-bearing plants (34.3%) and White flower-bearing plants (34%). Similarly, the percentage germination of pollen grains is high in pink flower-bearing plants (98.1%) followed by red-eyed flower-bearing plants (33.3%) and white flower-bearing plants (33.3%).

Effects of rapeseed oil (rapus indicus) supplementation on omega-3 fatty acid concentration and carcass characteristics in broiler chicken

Dietary fatty acid composition in broiler influences carcass quality by altering fat deposition and fatty acid profile. Thus, the study was carried out to evaluate the effect of incorporation of rapeseed oil in broiler ration on omega-3 fatty acid concentration of carcass and its traits in broiler chicken. A total of 160 day-old straight run broilers (Vencobb 400) were randomly divided into four treatment groups (G1, G2, G3 and G4) having four replicates of ten chicks each. The basal diets (G1) were prepared to meet BIS (2007) nutrient requirements with palm oil at 1.5, 3, and 4.5 per cent in pre-starter, starter and finisher diets, respectively. The experimental diets were broiler rations prepared with rapeseed oil replacing 25, 50 and 100 per cent of palm oil in G2, G3 and G4 diets, respectively. The diets were fed ad libitum till 6 weeks of age. Six birds from each group were randomly selected and slaughtered on 42nd day to study omega-3 fatty acid concentration of carcass and its characteristics. The crude fat content of breast and thigh muscle was significantly (P<0.05) reduced in the group fed rapeseed oil included diets. However, carcass yield, processing yield and meat to bone ratio of cut up parts was not significantly affected. The colour and pH of breast and thigh muscles were similar among the treatment groups. Omega- 3 fatty acid concentration was significantly (P<0.01) increased in both breast and thigh muscle of G4 group broilers compared to G1 group. Thus, rapeseed oil inclusion in diet significantly increased omega-3 fatty acid concentration and significantly reduced crude fat concentration breast and thigh muscles with no effect on the carcass yield and its quality when included in the diet replacing palm oil at different proportion

A memetic algorithm for the inventory routing problem

In this article, we study an Inventory Routing Problem with deterministic customer demand in a two-tier supply chain. The supply chain network consists of a supplier using a single vehicle with a given capacity to deliver a single product type to multiple customers. We are interested in population-based algorithms to solve our problem. A Memetic Algorithm (MA) is developed based on the Genetic Algorithm (GA) and Variable Neighborhood Search methods. The proposed meta-heuristics are tested on small and large reference benchmarks. The results of the MA are compared to those of the classical GA and to the optimal solutions in the literature. The comparison shows the efficiency of using MA and its ability to generate high quality solutions in a reasonable computation time.

Homogenous generation of dopaminergic neurons from multiple hipsc lines by transient expression of transcription factors

A major hallmark of Parkinson's disease is loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc). The pathophysiological mechanisms causing this relatively selective neurodegeneration are poorly understood, and thus experimental systems allowing to study dopaminergic neuron dysfunction are needed. Induced pluripotent stem cells (iPSCs) differentiated toward a dopaminergic neuronal phenotype offer a valuable source to generate human dopaminergic neurons. However, currently available protocols result in a highly variable yield of dopaminergic neurons depending on the source of hiPSCs. We have now developed a protocol based on HBA promoter-driven transient expression of transcription factors by means of adeno-associated viral (AAV) vectors, that allowed to generate very consistent numbers of dopaminergic neurons from four different human iPSC lines. We also demonstrate that AAV vectors expressing reporter genes from a neuron-specific hSyn1 promoter can serve as surrogate markers for maturation of hiPSC-derived dopaminergic neurons. Dopaminergic neurons differentiated by transcription factor expression showed aggravated neurodegeneration through α-synuclein overexpression, but were not sensitive to γ-synuclein overexpression, suggesting that these neurons are well suited to study neurodegeneration in the context of Parkinson’s disease.

Finance for decision makers

In their different ownership structures, business enterprises pursue different strategies towards accomplishing their owners’ needs and interests. At the heart of these accomplishments is the generation of sufficient financial returns to cover obligations as they become due and residual incomes for the owners. It is doubtless that without a grip of financial stability, the survivability of for-profit organizations becomes bleak. Financial management plays and instrumental role in this case. The generation of sufficient information for decision making for the business and investors alike is integrally critical in shaping the progression of the business enterprise. While businesses provide financial statements according to prevailing laws and accounting standards to the public for their consumption in decision making, they are further needed to be accountable to them regarding their performance and investors’ engagements, especially considering that investors are foundational sources of capital for organizational operations.

Budd-chiari syndrome in gaucher disease type iii in an adult libyan male: letter to the editor

Gaucher Disease (GD) is the most common lysosomal storage disorder. The prevalence of GD is approximately 1/100,000, and type III GD accounts for 5% of cases. [1] It is an autosomal recessive disease due to a GBA gene mutation, leading to glucocerebrosidase enzyme deficiency. [1,2] Gaucher disease (GD) is categorized into three types according to clinical presentation: [3] Type I, which is non-neuronopathic and most common, particularly among Ashkenazi Jews; Type II, which is acute neuronopathic and marked by significant neurological involvement and high mortality rates; and Type III, which is subacute neuronopathic, exhibiting both systemic and neurological symptoms. In this report, we discuss a 24-year-old man from Libya diagnosed with GD type III. His diagnosis was established at the age of one due to symptoms including pallor, poor appetite, and hepatosplenomegaly. Laboratory tests indicated a hemoglobin level of 5.6 g/dL, chitotriosidase activity of 18,742 μmol/L, and an angiotensin-converting enzyme level of 251 UI/L. Genetic analysis confirmed a homozygous L444P mutation. He underwent splenectomy at the age of three, and enzyme replacement therapy (ERT) was administered intermittently with regular follow-ups until 2011. In December 2023, the patient experienced two weeks of abdominal pain, distension, and fatigue. A physical examination revealed ascites, dilated abdominal veins, and an enlarged liver and spleen.

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.

Schwannoma with an unusual anterior chest wall location: a rare case report

Chest wall schwannoma is a rare intercostal nerve tumor originating from Schwann cells. Here, we present a case of a 44-year old woman who presented with symptoms of cough, fever, and left-sided chest pain. A plain chest radiograph was unremarkable and was further evaluated with a contrast-enhanced chest computed tomography (CECT) scan, which showed a well-defined, encapsulated soft-tissue mass in the left anterior first intercostal space. The diagnosis of schwannoma was based on histopathological and immunohistochemical studies of tissue biopsies taken from the lesion. The patient was referred to a higher oncology center for further treatment where he received symptomatic treatment for the pain and cough after which he improved. The patient was discharged and followed up in the clinic. Six months later, the patient underwent another chest CECT, which revealed no growth in size from the first one. Therefore, it was decided to keep the patient in regular follow-up since the lesion remained stable in size.

Symmetric key cryptosystem based on randomized block cipher

Multimedia data encryption attempts to prevent unauthorized disclosure of confidential multimedia information in transit or storage. Security of multimedia files attracts more and more attention and many encryption methods have been proposed in literature. If we call a multimedia data stream (message) plaintext , the process of transforming the plaintext into unintelligible data stream is referred to as multimedia encryption (MME) where the encrypted message (data stream) is often named ciphertext. The process of transforming the ciphertext back into plaintext is termed decryption. We propose a new block cipher based on randomized key of size n × n where n is the block size and the block undergoes n 2 iterations with the plaintext. Every iteration generates the pseudo cipher text. The encryption process generate the ciphertext C with the help of the randomized key. The decryption apply the key in reverse order on the cipher text, to get back the plain text. This work deals with the problem of efficient multimedia data encryption.

Comparison between isoflurane and sevoflurane in inhalation anesthesia: a prospective study

Inhalation of a gas anesthetic produces rapid induction of anesthesia without the need for intravenous drugs. Although it is specifically useful for patients who are afraid of injections or if their intravenous access is difficult, single-breath induction may also allow patients to wake up more quickly than intravenous induction drugs. The object of this study is to compare isoflurane and sevoflurane during inhalation in Libyan patients undergoing surgery in terms of side effects like blood pressure and heart rate changes and complications. Seventy- five patients were recruited in this study from different hospitals in Benghazi City, Libya (January to March, 2022) including Aljalaa Hospital and Alatfal Hospital, and data including side effects and complications were collected through data collection. Surgeries that used isoflurane, or sevoflurane or both inhalation gases for anesthesia were included in our data. While the surgeries which did not use any of these inhalation gases were excluded from our data. When we compared the side effects of using isoflurane with sevoflurane according to the age group, we found that hypotension is the most occurring side effect companies to the use of isoflurane in our adult population (28.6%) and in pediatrics (14.3%) but there was a low incidence of other side effects related to sevoflurane administration. Regarding to side effects related to the use of sevoflurane according to the age groups, 16 adult Libyan patients experienced no side effects (61.5%) compared to 10 children (38.5%). It can be concluded that both isoflurane and sevoflurane are suitable for daycare anesthesia. Sevoflurane might be an ideal drug for single-breath inhaled induction of anesthesia due to it has fewer side effects and complications.

Growth of brushite crystals on glass slide: a simple and inexpensive in vitro model to evaluate natural antiurolithiatic drugs

The kidney contains mineral deposits in various phases of calcium salts, such as calcium oxalate and calcium phosphate. Calcium hydrogen phosphate dihydrate (CaHPO4.2H2O) / brushite is a stable form of calcium phosphate, which exists in the form of kidney and bladder stones. The study aimed to explore the possible morphological features of brushite crystals. The study was carried out on a glass slide under a microscope to observe the growth patterns of these crystals. For this purpose, a drop of gel medium (sodium meta silicate solution + 1M orthophosphoric acid solution) at pH 4.99-5.09 was placed in the middle of a glass slide and converted into a gel. A 1M calcium chloride drop was added to form the gel adequately. The glass slide was observed under a microscope till it was completely dried. Calcium hydrogen phosphate dihydrate was formed as elementary needles, needle clusters, an assemblage of needles with platy crystals, plates with spatial branches, radiating assemblage of platy crystals, star shape crystals and tetragonal bipyramidal. The Current study provides brushite crystallisation phases on glass slides for the first time. It may also be used as a model to evaluate prophylactic management against renal stones through in vitro assessment of crystal growth and aggregation inhibition and modulation of developing or developed crystals by using different natural products. However, it was a preliminary study with no quantitative or statistical analysis.

Aqueous extract of hybanthus enneaspermus exhibited aphrodisiac potentials in fluoxetine-induced sexually-impaired female rats

Hybanthus enneaspermus, traditionally used as an aphrodisiac was investigated for its potential to reverse antidepressant-induced sexual dysfunction in female rats. The aqueous extract was evaluated for secondary metabolite, amino acid and mineral constituents. Alkaloids, tannins, flavonoids, anthraquinones, steroids, terpenoids, phenolics, calcium, potassium, sodium, glutamine and leucine are some of its notable constituents. 60 healthy, sexually responsive female albino rats (144.7±5.9 gm) were divided into six groups (A-F) of 10 rats each; of which 50 were induced into sexual dysfunction. Rats in group A were administered distilled water throughout the experimental period and served as a control group, while rats induced into sexual dysfunction (Groups B-F) by fluoxetine were given water, the reference medication (Tadalafil) and oral doses of the extract (250, 500, and 1000 mg/kg body weight) once daily for seven days, respectively. When administered to sexually active rats, fluoxetine significantly decreased the frequency of darting, hopping, lordosis, genital grooming, and licking behavior by 57.4%, 42.5%, 43.9%, 64.0%, and 41.8%, respectively. However, the latency of darting, hopping and lordosis were significantly increased by 50.6%, 47.7%, and 54.9%, respectively. Hybanthus enneaspermus aqueous extract administered at doses of 250, 500, and 1000 mg/kg significantly reversed fluoxetine-mediated changes in all sexual behavior parameters. The extract's ability to reverse the characteristics of sexual behavior at 1000 mg/kg was comparable to those of tadalafil-treated rats. Additionally, all the extract dosages reversed the levels of blood luteinizing hormone, follicle-stimulating hormone, progesterone, prolactin and estrogen after it has significantly been altered by fluoxetine. The results indicated that the aqueous extract of Hybanthus enneaspermus improved the proceptive, receptive and orientational behavior of rats. The extract also enhanced reproductive hormone concentration by restoring sexual competence in sexually-impaired female rats. The findings of this study provide further evidence in favor of Hybanthus enneaspermus widespread usage in the management of female sexual dysfunction.

Impact of foreign universities on indian higher education

The planned opening of foreign universities will foster cultural exchange, expose Indian students to diverse perspectives and promote international understanding, according to Gedam Kamalakar. Foreign university campuses have the potential to attract foreign investment, create job opportunities and stimulate the local economy through increased spending on infrastructure, accommodation and services. Partnerships with foreign universities on joint research projects will enhance knowledge exchange and technological advancements. Nevertheless, the influx of foreign universities can pose a threat to domestic educational institutions by alienating talented students and faculty and exacerbating inequalities in access to quality education. There is hence a danger of cultural imperialism. Indigenous knowledge and traditions may be marginalised due to the dominance of Western educational systems and values. Increasing opportunities to study abroad may also increase brain drain.

Assessment of drug prescribing pattern and prescription errors in elderly patients

The rate of aging is rapidly increasing and the term of geriatric refers to offer a medical care to elderly people. Drug consumption study on geriatric population is a vital issue since this group is totally neglected in Libya. The aim of this study was to assess drug utilization pattern among elderly patients in terms of world health organization core prescribing indicators and to evaluate the treatment cost. A total of 106 prescriptions were randomly collected from different community pharmacies located in Tripoli during the summer 2019, and were evaluated (total number of prescribed drugs is 359) for their clinical efficacy and safety. The findings revealed that 60 drugs acting on GIT (16.7%), 50 antimicrobial drugs (13.9%), 31 antihypertensive drugs (8.6%) and 30 drugs for respiratory diseases (8.4%) were prescribed to patients who are 65 years old or more. With regard to disease pattern in the elderly Libyan patients, 27 drugs were prescribed for diabetes mellitus (7.5%), 24 drugs for cardiovascular drugs (6.7%) and 14 drugs for anti-hyperlipidemia (3.9%). According to the WHO core drug use indicator pattern, the average number of drugs prescribed per encounter was 3.3. Prescription by generic name was low (41.5%). Antibiotics were 36.8% while injections were 26.6%. Thus, this study suggest that geriatric medicine and rational drug use should strongly be implanted in medical schools and teaching hospitals. Besides, a drug pattern use of the Libyan community is urgently required to avoid drug prescribing errors.
