Salah satu cara Allah mendidik hambanya adalah melalui kisah-kisah yang terdapat dalam al-Quran. Akan tetapi pada saat sekarang ini orang sudah mulai meninggalkan kisah-kisah al-Quran tersebut dan menggantinya dengan kisah-kisah fiktif yang minim dengan unsur-unsur pendidikan. Dengan menggali kisah-kisah yang terdapat dalam al-Quran maka kita akan mendapatkan nilai-nilai pendidikan yang disajikan dalam Kisah tersebut. Penelitian ini adalah penelitian kualitatif dengan bentuk Library Reasearch. Dalam penelitian ini data diambil dari buku-buku ataupun jurnalyang memiliki kaitan dengan judul penelitian ini. Dari penelitian ini peneliti menemukan nilai-nilai yang terkandung dalam kisah as-habul Jannatin. Nilai-nilai pendidikan tersebut adalah: Etos Kerja yang tinggi, Menjauhi gaya hidup Hedonis, dan berkomunikasi secara Qurani. Nilai-nilai tersebut akan memberikan implikasi yang baik terhadap pembentukan akhlaq.

Published: March 2022

Context.—
A prolonged activated partial thromboplastin time (APTT), a vital screening test for coagulation, can be due to deficiencies in coagulation factors and the existence of factor inhibitors or antiphospholipid antibodies. APTT mixing studies are being optimized to help find the cause.

Objective.—
To optimize APTT mixing studies, we evaluated existing standards and explored when and how to combine 1:1 and 4:1 mixing.

Design.—
Patients with a prolonged APTT but otherwise normal prothrombin time and thrombin time were enrolled in our hospital from January 1, 2018, to December 31, 2019. All samples were subjected to 1:1 mixing studies, while 134 were subjected to 4:1.

Results.—
A total of 251 samples were involved, including 116 with factor deficiencies, 75 with FVIII inhibitors, and 60 with antiphospholipid antibodies. A Rosner index less than 11% or an extended incubation time of more than 3 seconds was better than other existing standards in differentiating factor deficiencies from inhibitors and in differentiating time-dependent inhibitors from time-independent inhibitors, but the approach presented here improves upon those. For the best diagnostic accuracy, samples with a Rosner index between 5.0% and 9.1% need a 4:1 mixing study, while others need 1:1. A combination of Rosner index and percent-extended incubation time-P seemed to offer objective and effective criteria for interpreting the results.

Conclusions.—
APTT mixing studies had overall good sensitivity and specificity in differentiating factor deficiencies from inhibitors, or time-dependent from time-independent inhibitors. The combination of 1:1 and 4:1 mixing studies can improve the diagnostic ability compared with 1:1 alone.

ABSTRACT
Introduction: COVID-19 is a novel pandemic that has had a profound impact on global physical and psychological health. We aimed to investigate the impact of COVID-19 on stress, sleep quality, and insomnia among South Valley University students in Egypt during the quarantine period.
Material and Methods: A questionnaire, including the Pittsburgh sleep quality index, the insomnia severity index, the perceived stress scale and COVID-19 fear index was distributed to the undergraduate students through the online platforms of South Valley University during the period of 1st to 15th June 2020.
Results: Of a total respondent sample of 2,474 students, 24.5% had high-perceived stress levels, 31.3% had clinical insomnia, and about 80% were identified as generally poor sleepers by the PSQI. Being female, having a chronic disease, having a sleep disorder before the quarantine, or consuming caffeine were the main factors associated with high stress levels, clinical insomnia, and poor sleep quality. Also, levels of fear of COVID-19 were higher among people with high stress levels, clinical insomnia, and poor sleep quality. Conclusion: Considerable levels of stress and poor sleep quality were identified among undergraduate university students during the pandemic/home isolation period. The effect was more obvious among certain demographic groups and among the students who scored higher in the fear of COVID-19 scale.
First observations of ovary regeneration in an amphipod, Ampelisca eschrichtii Krøyer, 1842
Authors: Durkina Valentina B. , Chapman John W. , Demchenko Natalia L. 
Published: March 2022

Background
Females of the gammaridean amphipod Ampelisca eschrichtii with signs of regenerating, previously atrophied ovaries were recovered from the northeastern shelf of Sakhalin Island (Okhotsk Sea, Russia). Ovarian regeneration was previously unknown for any amphipod species. A. eschrichtii have a predominantly 2-year life cycle (from embryo to adult death) and reproduce once between late winter or early spring at the age of 2 years. Occasionally, females survive to a third year. An adaptive value of extended survival among these females is likely to require that they are also reproductive.

Methods
Histological sections from a second-year female with ovarian atrophy, a female with normal ovaries, a third-year female with ovarian regeneration, as well as testes of an immature and a sexually mature male were compared to determine the sources of cells of the germinal and somatic lines necessary for ovarian regeneration.

Results
Ovarian regeneration in the third-year female began with the formation of a new germinal zone from germ cells preserved in the atrophied ovaries and eosinophilic cells of the previously starving second-year female. Eosinophilic cells form the mesodermal component of the germinal zone. A mass of these cells appeared in the second-year female that had atrophied ovaries and in large numbers on the intestine wall of the third-year female with regenerating ovaries. These eosinophilic cells appear to migrate into the regenerating ovaries.

Conclusions
All germ cells of the second-year female are not lost during ovarian atrophy and can be involved in subsequent ovarian regeneration. Eosinophilic cells involved in ovarian regeneration are of mesodermal origin. The eosinophilic cell morphologies are similar to those of quiescence cells (cells in a reversible state that do not divide but retain the ability to re-enter cell division and participate in regeneration). These histological data thus indicate that eosinophilic and germ cells of third-year females can participate in the regeneration of the ovaries to reproduce a second brood. The precursors of these third-year females (a small number the second-year females with an asynchronous [summer] breeding period and ovaries that have atrophied due to seasonal starvation) appear to possess sources of somatic and germ cells that are sufficient for ovarian regeneration and that may be adaptations to starvation stress.
Enhancing Students’ Understanding of Abstract Concepts in Physics by Integrating ICT in Teaching-Learning Process
Authors: Tenzin Sangay , Tendar Pema , Zangmo Nidup 
Published: March 2022

Conceptualizing abstract concepts in physics has been a challenge that has impeded the learning and performance of the students in the schools in Bhutan. The advent of science and technology has led to development of numerous Information and Communication Technologies (ICT) that are apt to use in physics education but are hardly explored and used in the Bhutanese education system. Thus, there is a compelling need to revamp the conventional instructional approach to accommodate the modern physics education system. A quantitative quasi-experimental pretest-posttest control group design study was used to enhance students’ performance in physics by integrating ICT in the teaching-learning process at Chundu Armed Force Public School, Haa. Two rounds of data (baseline and post-intervention) were collected from both experimental classes (IX C and IX D) and control class (IX E) having 30 students in each section. The data were gathered through valid survey questionnaires, physics achievement tests, and classroom observation techniques between July and August 2021. The collected data sets were analyzed and triangulated using SPSS-22 and Microsoft excel 2011.
The study revealed 100% of participants’ preferences over ICT based approach to the conventional “chalk and talk” method in learning physics. The use of ICT facilities in the teaching and learning process has put the abstractness of physics concepts out of question and has enabled more entertaining, engaging, effective, and meaningful learning. It was evident with the significant increase in the mean score of students’ performance in the physics achievement test from 38.26 to 56.19, which account for 46.9 % for the experimental class. The opposite trend was also found for the controlled class with a mean-score difference of -0.12. Thus, the study suggests integrating ICT in teaching learning of physics to encourage two-way interactive delivery methods and enhance students’ performance in physics.

Published: March 2022

Introduction: The neutrophil lymphocyte ratio (NLR) is a cheap and readily available tool that is becoming increasingly recognized as a marker of pan-systemic inflammation. Gender differences have been identified in various inflammatory responses and play significant roles in the etiopathologic, epidemiological, clinical and prognostic profile of most disease entities. We assess gender association with the NLR.
Methods: One hundred and eighty eight participants (44 with acute kidney injury and I44 with chronic kidney disease were studied. Data on socio-demographics, clinical and laboratory findings such as NLR, serum electrolytes, albumin, uric acid and urine albumin creatinine ratio (UACR) were documented and gender associations of participants’ variables were determined.
Results: The NLR was higher in CKD than AKI, P=0.04, higher in females, P<0.001 and aged, P<0.001. The NLR was positively related to the platelet-lymphocyte ratio (PLR), albumin creatinine ratio, P=0.01 and the severity of the inflammatory condition. The men had higher serum albumin, creatinine, uric acid and UACR. The uric acid was higher in AKI than in CKD, P=0.04. The systolic blood pressure was higher in AKI than CKD, P<0.001. The serum bicarbonate was lower in AKI than CKD, P=0.04. In the elderly population, the proportion of females was more, P<0.001.
Female gender (OR-3.22, 95% CI-1.88-3.78), aging (OR-6.20, CI-3.17-9.58), smoking (OR-5.86, CI-4.52-8.95), elevated systolic blood pressure (OR-3.75, 95% CI-1.83-4.03) and elevated serum creatinine (OR-5.73, 95% CI-1.65-5.89) independently predicted elevated NLR.
Conclusion: The NLR is a readily available and cheap tool that was positively correlated with the age, BMI, blood pressure and inflammatory markers such as serum uric acid and UACR. It was higher in CKD than AKI, and in females. Being positively related to other inflammatory markers, it can be used in assessing the severity, prognosticating and perhaps predicting the outcome of inflammatory conditions.

Aim: To assess the levels of some gonadal hormones in lead-acetate-induced Albino Rats treated with Hypoestes rosea Leaf.
Study design: Experimental study.
Place and Duration of Study: Department of Pharmacology, University of Port Harcourt and Department of Medical Laboratory Science, Rivers State University, Port Harcourt, between October, 2019 and March, 2020.
Methodology: A total of 140 albino Wistar rats were used for this study. The animals were divided into 26 groups (6 post-treatment and 6 pre-treatment groups for female rats and the same number for male rats and 2 groups as male and female controls). Each group contained 5 rats for both sexes in both pre- and post-treatments groups, except the positive control groups that had 10 animals for both sexes. The study was carried out for 21 days. The negative control groups received rat feed only, extract control (EC) group received 100mg/kg bwt/day for 21 days, positive control (PC) group received 60mg/kg b.wt per day of lead acetate for 7 days. The other 3 groups received 100mgkg, 200mg/kg and 300mg/kg b.wt respectively for 14 days either as pre-treatment or post treatment, for both sexes of the albino rats. At the end of the experimental periods, the rats were sacrificed under chloroform anesthesia and samples were taken through the jugular vein. Reproductive hormone levels were estimated using the Enzyme linked immunosorbent assay methods. Statistical analysis was done using Statistical Analysis System (SAS), STAT 15.1 and p values less than 0.05 were considered statistically significant.
Results: Results showed lead acetate had significant negative effect (p<0.05) on most reproductive hormones, except LH and TSH (p>0.05). The plant in a dose dependent pattern was able to significantly (p<0.05), reverse the effect of lead acetate in the Post treatment phase and also protect the endocrine system from the deleterious effect of lead acetate in the pre-treatment phase. Testosterone was significantly reduced (p<0.05) in all the treatment groups that had the extract.
Conclusion: Our study showed that dose dependent AEHR extract significantly reduced the impact of lead intoxication on some hormones.
