In this paper, investigations are made to analyze the human body temperature during wound healing process due to surgery. Wound is considered after the skin graft. Skin graft is a technique used in plastic surgery. Skin is the first line of defense between the human and environment, it is very susceptible to damage. Internal body or core temperature (Tb) is one of the clinical vital signs along with pulse and respiratory rates. Any disturbance in body temperature will drive complexities in wound healing process. These studies are important in the mechanism of establishing the limits of thermal regulation of human body during the healing process in different situations and conditions. The Finite element method is used to analyze tissues temperature for normal tissues (donor site) and abnormal tissues (tissues after surgery). Appropriate boundary conditions have been framed. Numerical results are obtained using Crank Nicolson Method.

Physically unclonable function (PUF) is a hardware security module preferred for hardware feature based random number and secret key generation. Security of a cryptographic system relies on the quality of the challenge-response pair, it is necessary that the key generation mechanism must unpredictable and its response should constant under different operating condition. Metastable state in CMOS latch is undesirable since it response becomes unpredictable, this feature used in this work to generate a unique response. A feedback mechanism is developed which forces the latch into the metastable region; after metastable state, latch settle to high or state depends on circuit internal condition and noise which cannot be predicted. Obtained inter hamming variation for 8 PUF is 51% and average intra hamming distance is 99.76% with supply voltage variation and 96.22% with temperature variation.

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.

Ayurvedic formulations are of three types, Herbal, Mineral and Herbo-Mineral. Of which, Herbomineral is prepared either by Khalweeya or by Bhasmeekarana procedures. The quality of Bhasma depends on the number of putas given. Rasa Bhasma is one such kind of a Herbo-mineral preparation which can be obtained by Puta procedure as described in texts of Rasa Shastra. Though there are different procedures mentioned for preparation of Rasa Bhasma, maarana done with Gorvara puta seems to be an apt way to obtain the final product. Puta is the generalised way of heat application used during the pharmaceutical procedures of Rasa dravyas, where the purified organic Metal/Mineral is converted completely into powder form which can be absorbed easily into the body without causing any ill effects. Different types of Puta have been explained for bhasmeekarana of different metals and minerals. Among them, certain putas have been mentioned where Mandaagni plays a crucial role in Maarana (Incineration). These Mandaagniputas are in use of preparing certain Bhasmas like ShilajitBhasma, HaratalaBhasma, GouripashanaBhasma, and PaaradaBhasma. As these drugs are having relatively low boiling and melting points when compared to other dravyas, and are easy to evaporate when exposed to high temperatures, they need a standardized quantum of heat by which they can be transformed into Bhasma. Gorvara puta is one such kind where agni plays a major role in the preparation of Bhasma. So, the present study A Comprehensive Study of Gorvara Puta in Preparation of Rasa Bhasmahas has been under taken.

Rasa aushadhis are known for their uniqueness in curing the diseases with a very low dosage. These formulations are divided into two types based on their mode of preparation i.e., Single drug and Compound drug formulations. Based on their origin, the drugs are divided into three types, Herbal, Mineral and Animal. Any of these two or three together is combined to make a compound formulation. Apart from these, the other major factor which is needed for a formulation is the Rasa Panchaka of a Drug. Many of the formulations are being prepared based on their availability, keeping their Rasa Panchaka and Samprapti vighatana in mind. These formulations are designed in such a way that two or more drugs will be having one common quality, or Opposite Qualities or an Antidote of a particular Vishadravya, which can help in curing the disease. So an attempt is made to Review Tribhuvanakeerti Rasa with its Probable mode of action.

A medication error is any preventable event that may cause or lead to inappropriate use of drugs or patient harm if it is not under the control of the health care professional. Despite the fact that healthcare professionals take the responsibility very seriously, it has been estimated that 250 000 Americans die annually due to medication errors. Although, estimates show that one in ten patients worldwide is affected by medication errors while receiving hospital care, the harm can be caused by a range of incidents or adverse events. The exact incidence of medication errors in the neonatal intensive care unit (NICU) is unknown. In neonates especially premature infants, the immaturity of developing body systems affects the absorption, distribution, metabolism and excretion of drugs and therefore an exponential risk for medication errors is present. The risk of medication errors in children are much greater than adults.

Hypertension is a public health issue that significantly increases the risk of health problems and decreases health quality of life of the patients. Angiotensin converting enzyme inhibitors are used to control hypertension by preventing production of angiotensin II in turn decrease blood pressure, thus it may enhance the quality of life. This study aims to assess the effect of angiotensin converting enzyme inhibitors on the quality of life of patients with hypertensive aging 40 years or older in Benghazi city in comparison with other classes of hypertension medications. A case control observational study was conducted, adopting the structured face-to-face interviewing survey technique. Over 150 patients who visited Benghazi medical center during the study period (November, 2019 to March, 2020), to follow up their chronic disease. The investigators used a pre-validated, pre-piloted questionnaire that has been adopted from SF 36 and modified according to the updated literature review; responses to each question were coded and analyzed. The results display that antihypertensive medications were found to be significantly related to the limitation on the physical activity domain and found that medications decrease the limitation on the activity with about 20% of the patients who taking angiotensin receptor blockers (20%) and 30% of the patients taking angiotensin converting enzyme inhibitors, 40% of the patients had no limitations on bending kneeling and stooping. Moreover, on the limitations on walking more than one kilometre, the results were about 15% of the patients taking angiotensin receptor blockers and 30% of the patients taking angiotensin converting enzyme inhibitors had a slightly or no limitation on walking more than a kilometre. Thus, the findings indicate that antihypertensive medications have a positive effect on quality of life of the patient in limitation on activity domain but no conclusive difference was found between angiotensin converting enzyme inhibitors and angiotensin receptor blockers medications.

This study's objective was to determine the distribution of allele frequencies of CYP2C9 and CYP2C19 gene polymorphisms among the Papuan population, known as the second-largest ethnic group in Indonesia. According to recent research, there is a decrease in CYP2C9 and CYP2C19 produced by humans globally, including in Indonesia. These gene polymorphisms aid in the transmission of various endogenous and exogenous drugs in the human body. Material and Methods: A sum of 99 subjects, comprising 73 male and 26 female subjects aged 20-30 years, were used for this research. PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) analysis using AvaII, NsiI, and SfaNI enzymes tested for the genotypes CYP2C9 and CYP2C19 administered. The distribution of genotypes was calculated in the population (P<0.05) using the Hardy-Weinberg equilibrium. The Faculty of Medicine Gadjah Mada University's Medical and Health Research Ethics Committee (MHREC) accepted this research with written consent. The results revealed that in Papua subjects, CYP2C9*2 (rs1799853) and CYP2C19*17 (rs12248560) alleles were absent while in 17 percent of the population CYP2C9*3 (rs1057910) allele frequency was. In conclusion, CYP2C9*3 has the highest polymorphism rate in Indonesia, with the absence of CYP2C9*2 and CYP2C19*17. Therefore, genetic drift can occur within this ethnic group.

Streptococcus bovis/gallolyticus was considered as lower grade pathogen involved in endocarditis. Recent accumulating evidence has suggested that Streptococcus bovis/gallolyticus plays an important role in the initiation and development of colorectal cancer. This study was aimed to address the association between Streptococcus bovis/gallolyticus and colorectal cancer among Libyan patients, to determine the dominant biotype of Streptococcus bovis/gallolyticus associated with colorectal cancer patients and to evaluate the antibiotic susceptibly patterns of isolated strains. The study involved 20 colorectal cancer patients, 20 patients with large adenomas polyp and 20 people with healthy colonic mucosa as a control group. All the candidates were subjected to colonoscopy and histopathological examinations and conformation. The suspected and normal cases were then diagnosed according to the protocol used by the medicine specialist and grouped in accord with the study aim. All biopsies were handled and treated to isolate the suspected positive colonies of Streptococcus bovis/gallolyticus. Of the 20 colorectal cancer patients, seven patients (35%) were found to be Streptococcus bovis/gallolyticus carriers, (95% CI 1.22 - 1.72, p < 0.05). Nine patients (45%) were diagnosed colorectal cancer positive at age above 60 years old, eight patients (40%) at age 40 - 60 years old and three patients (15%) at age bellow 40 years old. Also, nine out of 20 patients (45%) with large adenomas polyp were found to be Streptococcus bovis/gallolyticus carriers, (95% CI 2.16 - 2.71, p < 0.05). Of the 20 healthy people with colonic mucosa, Streptococcus bovis/gallolyticus never been isolated. Streptococcus. bovis biotype II/I and Streptococcus. equinis were both susceptible to the above mentioned antibiotic classes, although Streptococcus bovis biotype I was highly resistance to most clinically used antibiotics. However, there was strong relationship between Streptococcus bovis/gallolyticus and colorectal cancer or large polyp formation. However, it is not well understood whether the bacterium has a pathogenic role in the initiation and progression of neoplasia or just an epiphenomenon of colorectal neoplasms.

Tuberculosis is communicable disease which is common and often deadly infectious disease caused by mycobacterium tuberculosis. Tuberculosis continues to be a major public health problem in the world. The aim of this study is to assess prevalence and associated risk factors of pulmonary tuberculosis. Treatment and development of multidrug-resistant tuberculosis were also considered. Drugs for Pulmonary tuberculosis confirmed cases used in calculating tuberculosis prevalence in Libya which is obtained from archive department of Abu Seta Hospital. Data obtained from 427 files during 2019 determine the incidence and epidemiology of tuberculosis in Libya. For a total of 427 confirmed cases of pulmonary tuberculosis, about 75.0% of the cases were male and most of the patients (55.0%) were within the age group of 20 - 40 years old. Of the study patients, 114 patients (26.7%) were viral infected and most of the viral infected cases were in the age group of 20 - 40 years and the majority of this age group patients (n = 41, 53.2%) were infected with HIV/HCV, while the least percentage in this group age were infected with HIV/HBsAg (01.3%). Among 427 cases, 73 cases (17.1%) were comorbid with other chronic diseases. Of the 73 cases, 54 cases (74.0%) were diabetes mellitus whereas only 1.4% of them had bronchial asthma, Parkinsonism and renal failure. The drug therapy of active tuberculosis disease needs combination chemotherapy to escape the selection of naturally occurring drug-resistant mutants. Amongst current anti tuberculosis drugs, the rifamycins hold the highest potential for shortening treatment and improving effects. Prevalence of smear positive tuberculosis and bacteriologically confirmed that a high rate of tuberculosis among unemployed population. This study reported that the highest incidence rate is found in people who are smokers.

The prevalence rate of vitamin D deficiency over the last decades has grown up rapidly worldwide among young adults. Therefore, the aim of this study is to explore knowledge, attitude and practice of Libyan medical students of Sebha University regarding vitamin D deficiency. Out of a total of 200 questionnaires, 148 completed questionnaires were returned (74.0% response rate). The majority of respondents did not measure their vitamin D levels (62.1%). Participants who indicated they exposing to sunlight for less than 15 min were 47.2% while 74.9% exposing to less than 30 min with highly significant difference in gender (p < 0.001). All the males did not use sunscreen creams compared with females (43.5%). Nearly two-thirds of the participants (61.4%) denied drink milk almost daily with significant differences based on the gender (p < 0.005) while 56.0 % of the participants reported eat fish, 60.8% of the students denied eating fast food and 74.3% eating eggs daily or weekly. However, 49.3% of the students are usually drinking of tea and coffee after meals, and do not usually practice exercise (53.3%), however, disagreed that their food has a low amount of calcium (30.4%). Most of the students agreed with the benefits of vitamin D (72.0%). Based on the assessment of awareness of the participants about vitamin D information, the average of correct answers percentage of the respondents was 47.1%. The most frequent sources of vitamin D information were the internet which accounted for 49.3%, followed by relatives and friends (31.7%). Some of the respondents (58.7%) reported that unawareness is the main cause of vitamin D deficiency. This study highlights the lack of awareness about the importance of vitamin D among medical students. This finding provides the institutions of medical education in Libya with an evidence base for a deficit knowledge regarding young health which could be utilized it to draw a strategy to correct health behaviors of students and community through medical education programs.

The propagation of using drugs on the road was the main reason for focusing on the development of the rapid methods which are used to detect the presence of drugs which may have been taken. Oral fluid has become a popular specimen to test for the presence of drugs. In vitro tongues were prepared with different concentrations of hydroxypropyl methyl cellulose (HPMC E4M); one of these concentrations was chosen to be used for tests. Chemical reagents were prepared which included: cobalt thiocyanate, fast blue B test, Marquis, Mandelin and Zimmerman reagents which were used to examine eight drugs in three different concentrations, each of 10.0 mg/mL, 05.0 mg/mL and 01.0 mg/mL where each reagent was used for a particular drug. The drugs were amphetamine, cannabis, cocaine, 3,4-methylenedioxymethamphetamine (MDMA), codeine, diazepam, heroin, methadone and morphine. Each drug was tested by a specific reagent. The difference in the concentrations gave various results in terms of achieving positive results and the ratio of the clarity of the colour. The amount of the drug on the tongue was between 20 μg and 400 μg. Positive and negative results were obtained in this study. Most of the high concentrations gave positive results; however, the low concentrations gave different results which were between positive, negative and light or very light in colour. In conclusion, there is an explanation of the difference in sensitivity of the effects of the different kinds of reagents in the drug, such as cobalt thiocyanate which was more sensitive at the low concentration of heroin and gave a clear result.

The 2019 coronavirus disease (COVID-19) was declared by the World Health Organization as a pandemic on 11th March, 2020 which spread rapidly all over the world. COVID-19 disease has different clinical presentations, ranging from asymptomatic to severe symptoms. Laboratory findings are important in determining which therapeutic strategies to seek and to identify severe cases initially. In this study, we compared the results of C-reactive protein, D-dimer, blood electrolytes and mean corpuscular hemoglobin concentration between survivors and non-survivors of 22 Libyan patients with COVID-19 present in the intensive care unit at Maitika Isolation Center (Tripoli, Libya) in the period of January to June 2021. We could not detect any significant difference in C-reactive protein between survivors and non-survivors but a significant difference in D-dimer level was observed. Non-survivor COVID-19 patients have a higher level of D-dimer. Moreover, a statistical significant difference in chloride and sodium levels but not in potassium level were detected. A marked lower of mean corpuscular hemoglobin in non-survivor than survivor COVID-19 patients was shown. Thus, these parameters could act as biomarkers for COVID-19 patients.
