Plants produce a diverse range of bioactive compounds making them rich source of different types of medicines. The plants are mostly cultivated for decoration and to enhance the appearance of houses, gardens, road sides, and also for commercial purposes such as floral decorations in form of bouquet. They are also source of fragrant oils for perfume making and cosmetic. However only very few of these plant species have found to be used in medicine and little or no literature exit on their chemical and biological activities. Araucaria columnaris is an ornamental plant, commonly known as Christmas tree, belonging to the family Araucariaceae. Plant resin was used for the present study, antibacterial activity and GC-MS analysis of Araucaria columnaris resin was carried out. The resin was subjected to solvent extraction using decreasing polarity solvents (aqueous, methanol, ethyl acetate and benzene). TLC profiling of all the extracts gives an idea about the presence of various phytochemicals and its fractions were checked for antibacterial activity against major clinical pathogens. It was found that fraction 4 (F4) of methanolic extact showed maximum zone of inhibition against Gram positive organisms. This fraction was subjected to GC-MS analysis; the result revealed the presence of a board range of many medicinal compounds and antioxidant activity of resin of Araucaria columnaris were identified.
The primary objective of this study is to conduct a comprehensive analysis of the relationships between liquid- ity (LIQ), capital structure (LEV), and fnancial performance (FIP). Additionally, we seek to investigate the indirect efect of liquidity (LIQ) on fnancial performance (FIP) by examining the intermediary role of the capital structure (LEV) of non-fnancial-listed companies in the Vietnamese stock market. This study utilizes PLS-SEM with a robust sample of 644 non-fnancial-listed companies in the Vietnamese stock market. The fndings suggest that liquidity positively infuences fnancial performance but negatively impacts capital structure. Conversely, capital structure negatively afects fnancial performance. Thus, liquidity indirectly enhances fnancial performance through capital structure mediation. This research result can provide suggestions for non-fnancial enterprises in making fnancial decisions to increase fnancial efciency by increasing the holdings of highly liquid assets to prevent risks and take advantage of new investment opportunities in the future. In addition, increasing the holding of highly liquid assets also reduces debt pressure and reduces interest costs, thereby increasing fnancial efciency. Our research shows that the relationship between economic factors is extremely complex; specifcally, our research shows the true nature of the positive impact of liquidity on fnancial performance, including direct positive efects and indirect positive efects through capital structure. In addition, our research results also show that non-fnancial enterprises that want to increase fnancial efciency need to pay attention to revenue growth, and non-fnancial companies with larger total assets (size) will have more advantages in increasing fnancial performance.

Tonsil stones, also known as tonsilloliths or tonsiliths, are usually tiny white or yellowish mineralized structures packed with organic debris and bacteria that develop in the enlarged palatine tonsillar crypt. Tiny tonsillitis is commonly detected in diagnostic imaging such as computed tomography (CT) and less so in panoramic radiography, with the prevalence increasing with age. Giant tonsilloliths are rare and most reported cases have been in adults, with only a few cases reported in the pediatric population. In this report, we described a 9-year-old girl who had suffered from halitosis for 6 months and odynophagia with oropharyngeal foreign body sensation for 2 weeks and was later diagnosed with a tonsil stone.
Araucaria columnaris is one of the ornamental plants of all over the world. It is commonly known as Christmas tree. In the present study tree exudates – resin from the bark of the Araucaria columnaris belonging to the family Araucariaceae were investigated for phytochemical and antibacterial activity. The resin was separately extracted with different solvents based on its polarity, water, methanol, ethyl acetate and benzene. The extracts were screened for phyto-chemical analysis, the result shows that methanolic extract involved in extraction of large number of phytochemicals when compared with other extracts and subjected to antibacterial assay against major human pathogens. Methanolic extract act as good inhibitory agent against major microorganisms. This finding revealed that methanolic resin extract of Araucaria columnaris had significant potential for the control of dreadful diseases causing human pathogens.
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
This research work aimed to evaluate the effects of thermal processing treatments on the nutrient anti-nutrient composition of Afzelia africana (Akparata) flour. The seeds were sorted, cleaned and processed into boiled, roasted and autoclaved lima bean flours. The flours obtained were analysed for proximate, vitamin and anti-nutrient contents using standard methods. The proximate composition of the samples revealed that the flours had a range of moisture, 8.23-12.40%, crude protein, 15.98-25.95%, fat, 21.00-28.21%, ash, 1.34-2.89%, crude fibre, 2.00-3.45%, carbohydrate, 38.68-49.33%, and energy 424.13 – 482.37kJ/100g, respectively. The vitamin contents of the flours showed that the samples contained 0.02±0.00 - 0.08±0.00mg/100g riboflavin, 0.78 - 1.98 mg/100g niacin, 0.40 - 0.89 mg/100g thiamine, 120.40-234.70mg/100g vitamin A, 72.11-134.19mg/100g ascorbic acid, 09.67-17.65mg/100g vitamin E, 310.60-430.60mg/100g B6, 3.47-5.87mg/100g B12, respectively. The result of the anti-nutrient composition of the flours also showed that the phytate, tannin, oxalate, cyanogenic glycosides, protease inhibitors, haemagglutinins inhibitors, levels of the samples were significantly (p<0.05) reduced by roasting and boiling treatments compared to the sample processed by autoclaving. In addition, the saponin content of the flours was relatively higher in boiled sample than in roasted and autoclaved flours. However, the nutrient and anti-nutrient contents of the flours observed that the flours have the potentials to be used as nutritional supplements in the preparation of a variety of food products than the raw sample.
In addition to the ordinary pharmacists’ role in dispensing and ensuring safety and efficacy of drugs, pharmacy profession is also concerning with clinical services towards community through multidisciplinary approach. In this regard, the clinical pharmacy is an area of pharmacy that concerned with the science and practice of rational drug use in which clinical pharmacist provides patient care that optimizes medication therapy and promotes health, wellness and prevention of diseases. During the recent crises of COVID-19 pandemic, the health systems appeared to be weak worldwide. Health care professionals seem to have nothing to present to their COVID-19 infected patients as no effective medications are approved by the World Health Organization (WHO) yet. Moreover, physicians are worried about the secondary infection for COVID-19 patients, therefore, treatment protocols were designed and mostly applied for critical COVID-19 patients who have been hospitalized in Libya. WHO does not recommend antibiotic therapy or prophylaxis for patients with mild COVID-19 unless symptoms of a bacterial infection exist. This monograph will highlight the widespread use of antibiotics and anticoagulants for COVID-19 patients at Maetiga Hopital in Tripoli, Libya

Using off-label drugs in obstetric-gynecology patients requires caution because of the high risk of pregnancy. Although there is still debate, data profiling its use in clinical practice is lacking. This study aims to observe the use of off-label drugs in obstetrics and gynecology patients in private hospitals, especially the pill Misoprostol. This study used a descriptive observational approach to hospital medical record data. Retrieval of research data retrospectively at Bunda General Hospital (X Hospital) for July 2017 – December 2017 and Sinar Kasih Hospital (Y Hospital) for January 2018 – December 2018. The number of samples was determined using the Slovin formula, with a systematic random sampling technique at X Hospital and total sampling at Y Hospital. The samples were 220 RM at X 130 Hospital and Y 90 Hospital. The research was conducted in the period January 2019 - March 2019. The results were analyzed univariately using several related references. The results showed 26.92% of misoprostol off-label use in X Hospital and 4% in Y Hospital. The off-label drug found was Misoprostol which belongs to the category of off-label indications (Missed Abortion, Incomplete Abortion, Blighted Ovum, and Induction of labor in cases of Serotinus, KPD, and IUFD), off-label doses (50 µg, 100 µg, and 400 µg), and off-label routes of administration (sublingual and vaginal).
The use of Capsicum annum L. for culinary purposes dates back centuries. Its medicinal benefits have also been investigated in the past few days. Analgesic and anti-inflammatory activity in 4 different colored (green, yellow, orange, and red) sweet bell peppers (Capsicum annuum L.) were investigated in 200 and 400 mg/kg doses. Current research is directed at authenticating whether Capsicum can be used as an analgesic and anti-inflammatory, comparing the effects of the most used analgesic aspirin. The effects of ethanol extract of Capsicum annum L. were determined for analgesic activity by acetic acid-induced writhing, tail immersion and hot plate test. Animals were divided into ten groups (n=7): (1) Control (2) CAG 200 (3) CAG 400 (4) CAR 200 (5) CAR 400 (6) CAO 200 (7) CAO 400 (8) CAY 200 (9) CAY 400 (10) Standard. All the extracts given intraperitoneally in rat hind paws of seven animals in each treatment group received 200, 400 mg/kg. Acute toxicity was also determined by increasing the dose to 3000 mg/kg, which showed no evidence of mortality. A statistical calculation was performed using SPSS software to compare the effects of aspirin and Capsicum extract. Positive results were obtained as compared to the control group; the analgesic effect was statistically significant (P˂ 0.05). These observations revealed that the fresh fruit extract of four kinds of Bell pepper at 200 mg/kg and 400 mg/ kg possesses anti-inflammatory and pain-suppressing activities possibly mediated via PG synthesis inhibition.
The main theme of this paper is to implement the mobility model in the Cooja simulator and to investigate the impact of mobility on the performance of Routing Protocol over Low power Lossy networks (RPL) in the IoT environment. In the real world, mobility occurs frequently. Therefore in this paper, a frequently used mobility model - Random Way Point (RWP) is used for analysis. RWP can be readily applied to many existing applications. By default, the Cooja simulator does not support mobility models. For this, the Bonn Motion is introduced into Cooja as a plugin. As IoT deals with the resource-constrained environment, a comparison is done between the static environment and the mobile environment in terms of power consumption. As expected, the results indicate that mobility affects the RPL in terms of Power Consumption

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%).
Worldwide, the focus on online learning during the era of the COVID-19 pandemic faced many challenges. The present study aimed to evaluate the preferences, perceptions, and attitudes of university students toward various strategies of learning. A pre-piloted cross-sectional survey was posted on the internet in Arabic and English language. Questions covered the demographical characteristics of the participants and their preferences and perceptions of various learning strategies. We received 270 questionnaires from various countries. The majority (n=199, 73.7%) of respondents were from the University of Sharjah, United Arab Emirates, with n=125 (46.3%) participants from the College of Pharmacy. The majority (n=198, 73.0%) of respondents were females, Arabs (n=262, 97.0%), living with their families (n=208, 77.0%), and with only the father working (n=174, 64.0%). Preference was, for online learning (n=145, 53.7%) as compared to in-class learning (n=119, 44.1%). More students (n=110, 40.7%) claimed improvement in their grades with online learning but 62 of students (23.0%) stated that their grades were worsened. Student’s performance in online exams was similar to that in paper exams. The majority (n=168, 62.2%) of students claimed that their overall expectations of online learning were not the same as those for in-class learning. 50.0%-60.0% of respondents believed that in-class learning allows them to learn more effectively, and achieve the best work preparation, best exam performance, and best education value, and they were more likely to recommend it. Despite the disadvantages of online learning, it remains the future strategy for higher education. Appropriate planning of courses, and helping students by reducing digital inequity, if any, would certainly prove satisfactory for the millennial generation of students

The disease has a significant clinical impact on patients, families, and caregivers through its progressive degenerative effects on mobility and muscle control. Available treatments for PD have varied results. Although there are anecdotal reports of improvement with Homoeopathy, there is a dearth of literature concerning usefulness in management of PD Objectives: To assess the usefulness of ultrahigh dilution of Zinc in the management of PD. Methods: A case of PD under standard care and refractory to treatment visited Out- Patient Department and was assessed with and Unified Parkinson’s Disease Rating Scale (UPDRS). As per the classical Homoeopathic guidelines Zincum metallicum 200 was prescribed after Repertorization. Results: UPDRS total score of 112 at baseline turned to 40 at the end of 1 year and 7 at the end of two years, in spite of reduction in the conventional medicines. Patient was on Stage 3 of Modified Hoehn and Yahr staging at the baseline and turned to Stage O in duration of 21 months. SEADL score has turned from 40% to 100%. Conclusion: Homoeopathic medicine Zincum met. is a valuable adjuvant in the management of Parkinson’s disease.
Plants produce a diverse range of bioactive compounds making them a rich source of different types of medicines. Ornamental plants are cultivated for adornment and to enhance the appearance of houses and also for commercial purposes. However, only very few of these ornamental plant species have found to be used in medicine and only little literature exit on their chemical and biological actions. In the present study, the evaluation of antimicrobial activities and identification of bioactive compounds using TLC and GC-MS of the A. columnaris bark extract were performed. In GC-MS bioactive compounds with medicinal value were identified, such as Benzoic acid, 1H-N-Hydroxynaphth (2,3) imidazole-6,7-dicarboximide, 2-Propenoic acid, 3-(4-methoxyphenyl), 1H-N-Hydroxynaphth (2,3-d) imidazole-6,7-dicarboximi. To prove the nontoxic nature of the plant, its crude bark extract was subjected to toxicity study using human embryonic kidney cell line. It reveal that the plant is minimal toxic to the human kidney cell line so usage of appropriate level will found to be safe and also carrying out some structural modification will help in the extraction of new drugs for pharmaceutical purpose.
Regularly used toothbrushes can be heavily contaminated with microorganisms, while inappropriate storage may increase the microbial load on these toothbrushes. Toothbrushes Microbial contamination can help to transmit many diseases, especially for people with mouth and/or Gum problems. This study aims to find the easiest and most available way to sterile toothbrushes at home. 24 adult volunteers were divided into four groups, the first three groups were asked to sterilize their toothbrushes with Dettol, water salt and hot water, while the fourth group toothbrushes were a positive control. Results showed that toothbrushes sterilized with Dettol gave the least contamination rate of 12.5%, toothbrushes sterilized with salt came next with 37.5%, while toothbrushes sterilized with hot tap water were the next with 50%. The toothbrushes of the fourth group which was used as the positive control were totally contaminated with different types of bacteria. Six bacterial agents were isolated; they are Staphylococcus Sp., Streptococcus sp., Bacillus Sp., E.coli, Pseudomonas Sp., and Salmonella sp. It was concluded that the use of Dettol was very effective in reducing the number of contamination of toothbrushes but its unacceptable flavour limiting its use. Other volunteers were comfortable with the use of salt and hot water as it was almost effective. The research suggests a group of recommendations to avoid the transmission of pathogens through toothbrushes and ensure healthy usage.
Different derivatives of Cinnamaldehydes were prepared by Claisen-Schmidt condensation (by using Strong basic reagent). The prepared Cinnamaldehydes were treated with Hydrazine hydrate in presence of ZnO Nano-catalyst under microwave assisted solvent-free conditions to afford different substituted Pyrazoles. Green chemistry was employed. Comparisons of both microwave & conventional methods were studied & found that the first was more potent than the later. The synthesized compounds were characterized by FT-IR, 1HNMR & elemental analysis. All synthesized compounds were screened for in vitro test against EAC cell lines. Most compounds exhibited good inhibitor potency with IC50 values.
