Pharmacognostic Studies on Curcuma Longa
Authors: Danapur Vijay
Published: September 2022

The turmeric (Curcuma longa) plant, a perennial herb belonging to the ginger family, is cultivated extensively in south and southeast tropical Asia. The rhizome of this plant is also referred to as the “root” and is the most useful part of the plant for culinary and medicinal purposes. The most active component of turmeric is curcumin, which makes up 2 to 5% of the spice. The characteristic yellow color of turmeric is due to the curcuminoids. Curcumin is an orange–yellow crystalline powder practically insoluble in water. Turmeric is used as a dietary spice, coloring agent in foods and textiles, and a treatment for a wide variety of ailments. It is widely used in traditional Indian medicine to cure biliary disorders, anorexia, cough, diabetic wounds, hepatic disorders, rheumatism, and sinusitis. Turmeric paste in slaked lime is a popular home remedy for the treatment of inflammation and wounds. For centuries, curcumin has been consumed as a dietary spice at doses up to 100 mg/d. Extensive investigation over the last five decades has indicated that curcumin reduces blood cholesterol, prevents LDL oxidation, inhibits platelet aggregation, suppresses thrombosis and myocardial infarction (MI), suppresses symptoms associated with type II diabetes, rheumatoid arthritis, multiple sclerosis (MS), and Alzheimer’s disease, inhibits human immunodeficiency virus (HIV) replication, enhances wound healing, protects from liver injury, increases bile secretion, protects from cataract formation, and protects from pulmonary toxicity and fibrosis, is an anti-leishmaniasis and an antiatherosclerotic. Additionally, there is extensive literature that suggests that curcumin has potential in the prevention and treatment of a variety of other diseases.

Authors: Gupta Monika
Published: September 2022

Cancer is a terrible disease and second leading cause of death, behind cardio-vascular disease in the world. At present, there are three main methods of cancer treatment: surgery, radiation therapy and chemotherapy. Pyrimidineis a six-membered heterocyclic aromatic organic compound containing two nitrogen atoms at positions 1 and 3. Pyrimidine derivatives occupy a distinct and unique place in chemotherapy. The chemotherapeutic efficacy of pyrimidine derivatives is related to their ability to inhibit vital enzymes responsible for DNA biosynthesis as dihydrofolatereductase (DHFR), thymidylatesynthetase (TSase), thymidine phosphorylase (TPase) and reverse transcriptase (RTase). In the present study involves synthesis of 6-Substituted pyrimidine 2,4-diones derivatives. The synthesized compounds were subjected to antimicrobial activity against Gram negative E. coli (MTCC 40) and S. aureus (MTCC 87). The synthesized compounds possessed good to moderate antibacterial activity. Compounds 1, 2, 3a possessed good antibacterial activity when compared with standard however the compounds 2a, 2b, 2d, 1b, 1d, 1e possessed moderate activity. 1c, 1d, 1a, 2e, 2c were observed to be totally inactive compounds.

Published: September 2022

Liquid emulsions have distinct advantages over other dosage forms by improving oral bioavailability as well as by reducing the side effects. On contrary, liquid emulsion exhibit lack of physicochemical stability and compliance issues. To overcome these problems, dry emulsion formulation recommended. Dry emulsions are formulated by spray drying, evaporation and rotary evaporation. The aim of the present investigation is to improve the dissolution and oral bioavailability of poorly water soluble drug Olmesartan medoxomil by preparing dry emulsion. Olmesartan medoxomil is poorly soluble drug used for treatment of high blood pressure, showing absorption window at stomach and upper part of small intestine. Dry emulsion was ready by victimisation purgative during which drug is very soluble, using poloxamer188 as water soluble carrier and aerosil 200 as an adsorbent. The preferred oils were castor oil, olive oil, soybean oil and isopropyl myristate and polymers were PEG400, Eudragit EPO and Poloxamer 188. Dry emulsion was prepared by spray drying. Dry emulsion was evaluated for drug content, percentage moisture content, aqueous solubility, dissolution study and in-vivo bioavailability study. In vitro drug release of dry emulsion was studied by using USP type II paddle dissolution apparatus. The solubility of the drug was increased with surfactant and polymer at 1:1 ratio. Probable mechanisms of improved solubility were characterized by particle size determination, Differential Scanning Calorimetry (DSC), Powder X-ray Diffractometry (PXRD) and Scanning Electron Microscopy (SEM). This study revealed that solid dry emulsion technique could prove promising for improvement of solubility, dissolution rate and oral bioavailability of Olmesartan medoxomil.

Authors: Cham Baboucarr
Published: September 2022

Cervical cancer is one of the commonest malignancy among women in the world with an estimated 527,624 new cases and 265,653 deaths in 2012.The burden of cervical cancer in developing countries is huge with an incidence rate that exceeds the average worldwide rates of 15.3 per 100,000 women per year. Furthermore, countries like Gambia, Mali, Uganda and Zimbabwe have age incidence rate of 32.5, 37.7, 47.5 and 47.4 per 100,000 women per year respectively. The aim of the study was to assess the Knowledge, Practise and Acceptability of Cervical Cancer Screening among Midwives in public health facilities in the Gambia. A cross-sectional study design was used and a sample size of 91 female midwives was selected from 14 public health facilities using multistage sampling method. A questionnaire consisting of structured and semi-structured questions was used. The questionnaire was pilot tested among 24 midwifery students for validity and had a Cronbach score of 0.76 after deleting six questions. Data was analyzed using SPSS version 20, descriptive and inferential statistics like hypothesis tested was performed. The results shows that 35.2% (n=32) had poor knowledge on cervical cancer, while 27.5% (n=25) had fair knowledge and 37.4% (n=34) had good knowledge on cervical cancer. There is no statistically significant association between length of service and knowledge on cervical cancer (P= 0.397). However, there is a statistically significant association between cadre and knowledge on cervical cancer screening as chi square test shows P= 0.006. There is knowledge deficit on cervical cancer among female midwives working in public health facilities in the Gambia. Very few midwives have been trained on visual inspection using acetic acid.

Authors: Backes Dirce Stein
Published: September 2022

The Brazilian Curriculum Guidelines for Undergraduate Nursing Courses have gradually encouraged home visits in differently realities by advocating the training of reflective and critical professional skills with regard to multiples dimensions of health of the human beings. Based on this justification, the objective of this study was to understand the meaning of the home visits for Brazilian nursing student in poor families. The Grounded Theory approach was used in this study. Data collection was performed between December 2017 and July 2018 through interviews with students and newly graduated nurses who are working in the Primary Health Care and carry out routine home visits. The meaning of home visits to poor families by a nursing student resulted in an intensive personal and professional (re)organization process: “I developed a professional attitude at the university, but among the poor families I developed personality”. Initially the students demonstrated uncertainty, disappointment and frustration, but soon as they take up the challenge, the nursing students rethink concepts, practices, types of personality and social responsibility. It is concluded that regular curricular activities with poor families have the possibility of extending the life expectancy of families and transcending the academic knowledge limits of students'.
Breast Cancer in Young Patients: Same or Different Entity?
Authors: Priego Paola Iturralde Rosas
Published: September 2022

Overview Breast cancer is the most common pathology in women of reproductive age; approximately 7% of breast carcinomas are diagnosed in women less than 40 years of age, corresponding to more than 40% of all malignant diseases diagnosed in this group. Genetic factors play a fundamental role in the genesis of the breast cancer in young patients. However, it is not easy to analyze them because their clinical usefulness is limited and there are multiple factors that must be considered. We conducted a retrospective study in which we included female patients of ages 40 years old or less, diagnosed with breast cancer at a private medical center during the period of January 2010 to July 2014. The protocol of the study included a complete clinical study, radiological reports as mammography and/or ultrasound image, histopathological and immunohistochemistry reports. The study included 46 patients with an average age of presentation of 37.1 years, a standard deviation (SD) of ±3.02 years and a median of 38 years. There were also different percentages for the various variables such as tumor characteristics, risk factors, and treatment provided. Young patients with breast cancer should be treated and evaluated individually by a multidisciplinary staff, as this pathological entity shows specific characteristics that makes this group of patients difficult to treat and warrants special considerations.
Maternal Related Factors Associated with Compliance to Iron and Folic Supplementation among Pregnant Mothers in Machakos County
Authors: Musyoki Matata
Published: September 2022

Iron is one of the essential nutrients that is responsible for synthesis of hemoglobin and whose demand increases during pregnancy. Iron and folate supplements are administered during pregnancy in order to cater for the increased demand during pregnancy to help supply the elements to both the fetus and the pregnant mother. According to the KDHS, 2014, in Kenya, the biggest challenge has been compliance to the supplements by the pregnant women, with only 14% of all pregnant women complying with the recommended schedule. This study therefore aims to examine the barriers that influence compliance to prenatal iron/folate supplementation among pregnant women in Machakos County. A facility based cross-sectional study was carried out in three sub-county hospitals within Machakos County. The facilities were randomly selected from seven sub-county hospitals. The study sampled a total of 204 pregnant women aged 18-49 years through systematic random sampling. Compliance to iron/folate was measured through Morisky medication compliance scale questionnaire. Data was collected through a structured questionnaire. Then organized and coded in to a computer software SPSS, version 24, for analysis. Logistic regression was done to assess possible associations and the strength of association was measured using odds ratio, with 95% confidence interval. Data was presented in forms of bar charts and tables. Three focus group discussions with health unit managers and administrators were done. The data from the focused group discussions was organized and emerging themes reported. Consent was sought before actual data collection.Results: Majority of the respondents were between 21 years and 40 years, with a few above the age of 40 years. Expectedly 84% were married and 76% had secondary level of education. More than half of the mothers were casual workers and 69% of them received family support during pregnancy. Among the socio-demographic factors of the respondents, family support and level of education of the mother were significantly associated with adherence to iron and folate supplements. Compliance to the supplements was improved when the supplements were given in combined form. Provision of health education in pregnancy especially counseling on nutritional value of supplementing iron stores in the body and how to manage side effects of iron and folate supplements were significantly associated with compliance to iron and folate supplements. Past experience of the mothers’ especially previous history of anemia, current haemoglobin level and bad obstetric history of the mother were found to increase compliance to the supplements. The study recommends the government of Kenya, through the County governments to develop policies on procurement and distribution of combined iron and folate supplement. This will promote availability of the drugs and improve compliance to the supplements.
Mobbing and Bullying in Workers, Pregnant Students and Parents who Work and Study
Authors: Valdivieso Rocío Fuentes
Published: September 2022

Mobbing, bullying and motherhood coupled with fatherhood in men and women who work and study, is considered part of the violence that is developing in the world of work according to the ILO (International Labor Organization). This research sought to study group violence such as mobbing and intimidation such as bullying when women become pregnant or become mothers. For this reason, we seek to analyze the impact of motherhood and fatherhood on men and women between 20 and 24 years of age, considered by the WHO (World Health Organization) to be full youth. We start from a generalized cultural assumption that men are able to bear the burden of study and work with greater skill than women and it is women who suffer more aggression. The questions that were sought to answer with this research are: Which group of women or men suffers more from group harassment, mobbing and intimidation accompanied by physical aggression such as bullying for being a mother or father? What are the types of violence you faced at school and at work for being a mother or father? The methodology for developing this study was qualitative and ethnographic. The techniques applied were in-depth interviews and case analysis. In addition to consulting various primary and secondary sources. It was interesting to study the modalities of violence in young men and women from 14 to 40 years of age. Our findings show that discrimination at school and at work was one of the main points of the interviewees. The aggression in the family was another reported data. At a younger age, violence against pregnant women is greater. Professionals are the ones who suffer the most aggression in their jobs when they become mother and father.

Published: September 2022

Objective: We present a case of acute intestinal ischemia and mesenteric venosus thrombosis in a first trimester pregnant woman with surgical treatment. Case presentation and intervention: Our case was a 23-year-old multigravid woman at 8 weeks gestation. She presented to Ataturk University Research Hospital with complaints of abdominal distention, nausea, vomiting and constipation. The first day after admission, complained of more intense vomiting, abdominal distenrion and pain. An emergency laparotomy was performed. The part of jejenum, entire ileum, part of the ascending colon were necrosis, and thrombosis was discovered in the mesenteric venosus. The necrotic intestine was resected and a end-to-end colo-jejunal anostomosis was perormed. Postoperative, the patient was started on anticoagulants and antibiotherapy in intensive care. Unfortunately, the patient died on the second day after the operation. Conclusion: Mesenteric ischemia and MVT in pregnancy is a rare, but important cause of intestinal ischemia. When a pregnant patient presents with an acute abdomen, mesenteric ischemia and MVT should be included in the differential diagnosis.

The Impact of Sex Education among Brazilian Adolescents
Authors: Drumond Denise Gasparetti
Published: September 2022

By entering into the reality of public schools in Juiz de Fora (MG), the present study aims to describe the scenario of adolescent’s sexual experience altogether with its risks and consequences, considering previous researches about Sexually Transmitted Infections (STIs) rates among the youth. One particular topic that needs attention is the female context, due to the fact that these diseases often have more severe consequences in women’s bodies, such as pelvic inflammatory disease (PID), ectopic pregnancy, and cervical cancer. Based on the assumption that well-informed people are more likely to adopt positive and healthy habits for themselves and considering the lack of knowledge on the topic among young Brazilians, schools symbolize an excellent place for having an informational dialogue. Therefore, the objective of the article is to describe the relation between health and education in the aforementioned scenario, from the perspective of the university extension project “Saber Viver”, conducted in the Medicine School at the Federal University of Juiz de Fora (UFJF). It expands the merely preventive methodology centered on biology into a more human approach, compatible with the socio-cultural context of the young audience. The project is also a key tool to guide public health policies that aim at reducing rates of Sexually Transmitted Infections (STIs).

Authors: Saleh Mustaruddin
Published: September 2022

The objective of this study to analyse the performance of banks before and after conducting Mergers and Acquisitions (M&A) using a risk approach and how it affects the value of banking companies. Banking performance was analysed from three years before and three years after conducting mergers and acquisitions. To analyse the impact of banking mergers and acquisitions on company value, paired sample t-test and the fixed effect model (FEM) and Random Effect Model (REM) are utilised to test the research hypothesis. The results show that the banking performance after conducting M&A is decreased. This is demonstrated by the improvement in banking value and performance by using variables PBV, Tobin’s q, LDR and COMIN, which increase relatively after mergers and acquisitions, but the ability to generate profits, as measured by ROA is decreased.This is an implication of the combination of large assets that have not been used optimally to generate profits.

Prediction analysis of the length of time for changes in the status of positive patients for covid-19 delta and omicron variants using the markov chain model
Authors: Haryanto Dwi , Addini Fida Fathiyah
Published: September 2022

In this research, a Markov chain model was constructed from the conditions that might be experienced by the people during the Delta or Omicron variant of the COVID-19 pandemic. This condition is divided into 3 states; "0" indicates a healthy condition, "1" indicates the state of being infected with COVID-19, and "2" indicates the death state. Furthermore, from the model obtained, a transition probability matrix is made to determine the transition probability value and calculate the average number of steps needed to get to the death state. From the results of the analysis, the probability of transition to a state of death is 1. This shows that a person will surely die from being healthy or positive for COVID-19 within a certain time. During the Delta variant of the COVID-19 pandemic, the average time that a person reaches a death state from a healthy state is 34.02 years. Meanwhile, the average time taken for someone infected with the Delta variant of COVID-19 to death is 33.79 years. During the Omicron variant of the COVID-19 pandemic, the average time that a person reaches a death state from a healthy state is 37.63 years. Meanwhile, the average time taken for someone infected by the Omicron variant of COVID-19 to death is 37.41. This shows that the average age of a person infected with the Delta variant of COVID-19 has decreased by 2.79 months, while the average age of a person infected with the Omicron variant of COVID-19 has decreased by 2.70 months.
Numerical analysis of blood flow in abdominal aortic aneurysm using finite volume method
Authors: Fatahillah Arif , Anggraini Azza Liarista , Setiawani Susi
Published: September 2022

There is a deadly cardiovascular disease that can cause swelling of the Abdominal Aorta. This disease is known as Abdominal Aortic Aneurysm (AAA). AAA is believed to be a degenerative process caused by genetic factors, gender, body weight, and age. Changes in collagen and elastin in the aortic wall are the cause of the degeneration process. Therefore, it will cause dilatation of the aortic wall. Swelling of the aortic blood vessels will affect the blood flow velocity in the aortic blood vessels. This research aims to analyze the velocity of blood flow in the Abdominal Aortic Aneurysm based on swelling diameter, proximal neck length, and aneurysm channel length using Computational Fluids Dynamics (CFD). The blood flow velocity was modeled using mathematical language based on mass continuity equations and momentum equations.  Then the finite volume method was one method to solve the mathematical model. MATLAB and ANSYS FLUENT software were used to simulate the velocity of blood flow analysis. The results of the research were shown that the larger the diameter and swelling channel length, the smaller the velocity of blood flow produced. Then, the greater the length of the proximal neck, the faster the resulting blood flow will be.

Redshift distances in flat Friedmann-Lemaître-Robertson-Walker spacetime
Authors: Haase Steffen
Published: September 2022

In the present paper we use the flat Friedmann-Lemaitre-Robertson-Walker metric describing a spatially homogeneous and isotropic universe to derive the cosmological redshift distance in a way which differs from that which can be found in the general astrophysical literature.
Using the Friedmann-Lemaitre-Robertson-Walker the radial physical distance is described by R(t) = a(t)r. In this equation the radial co-moving coordinate is named r and the time-depending scale parameter is named a(t). We use the co-moving coordinate r_e (the subscript e indicates emission) describing the place of a galaxy which is emitting photons and r_a (the subscript a indicates absorption) describing the place of an observer within a different galaxy on which the photons - which were traveling thru the universe - are absorbed. Therefore the physical distance - the real way of light - is calculated by D = a(t_0)r_a - a(t_e)r_e ≡ R_0a - R_ee. Here means a(t_0) the today’s (t_0) scale parameter and a(t_e) the scale parameter at the time t_e of emission of the photons. The physical distance D is therefore a difference of two different physical distances from a coordinate origin being on r = 0.
Nobody can doubt this real travel way of light: The photons are emitted on the co-moving coordinate place r_e and are than traveling to the co-moving coordinate place r_a. During this traveling the time is moving from t_e to t_0 (t_e ≤ t_0) and therefore the scale parameter is changing in the meantime from a(t_e) to a(t_0).
Using this right physical distance we calculate the redshift distance and some relevant classical cosmological equations (effects) and compare these theoretical results with some measurements of astrophysics (quasars, SN Ia and black hole). We get the today’s Hubble parameter H_0a ≈ 65.66 km/(s Mpc) as a main result. This value is a little bit smaller than the Hubble parameter H_0,Planck ≈ 67.66 km/(s Mpc) resulting from Planck 2018 data which is discussed in the specialist literature.
Furthermore, we find for the radius of the so-called Friedmann sphere R_0a ≈ 3,096.92 Mpc. This radius corresponds to the maximum possible distance of seeing within an expanding universe. Photons, which were emitted at this distance, are infinite red shifted.
The today’s mass density of the Friedmann sphere results in ρ_0m ≈ 7.82 x 10-29 g/cm^3. For the mass of the Friedmann sphere we get M_Fs ≈ 2.86 x 10+56 g.
The mass of black hole within the galaxy M87 has the value M_BH, M87 ≈ 2.36 x 10+45 g. The redshift distance of this object is D ≈ 19.45 Mpc but its today’s distance is only D_0 ≈ 6.27 Mpc.
