Medical students usually sacrifice their sleep to adjust to their workloads. It is worth noting the importance of a good night's sleep to ensure the body and mind's optimum performance. However, depriving oneself of much-needed sleep in exchange for productivity has been shown to have deleterious consequences on the students' physical health and their state of mind. The objective of this study was to investigate the association between sleep quality and mental health among International Islamic University Malaysia (IIUM) medical students in the COVID-19 era. A cross-sectional study was conducted from July 2021 until August 2021 in IIUM and all year 1 and year 2 medical students were invited to participate. A total of 158 students responded, consisting of 77 first-year and 81 second-year medical students. The survey was distributed to assess the sleep quality using Pittsburgh Sleep Quality Index (PSQI), the mental health status was measured using WHO-Five Well Being Index (WHO-5) for the depression level and the General Anxiety Disorder-7 (GAD-7) for the anxiety level. The association between sleep quality and mental health was tested using Pearson's chi-square test and Fisher's Exact test. The findings showed a significant association between sleep quality and the mental health of medical students. A higher proportion of participants (86.4%) with depressive symptoms had poor sleep quality. Similarly, 81.8% of participants with anxiety symptoms had poor sleep quality. There was significant association between sleep quality and depression and/or anxiety (p<0.001). This study has shown a significant association between sleep quality and mental health status among IIUM medical students. It is highly recommended that the university provide interventions including advertising good sleep hygiene and coping mechanisms to support students' mental health in this COVID-19 era

Medicine has a well-known reputation for being among the toughest courses to enrol in once a student step into college or university. Given the mounting pressure to excel in a high stake learning environment, undeniably their quality of life could be affected. With the added challenge of navigating online learning during a pandemic, the students’ well-being has become an issue of great concern. Therefore, this study aimed to evaluate the quality of life among preclinical medical students of International Islamic University Malaysia during COVID-19. We conducted an observational cross-sectional study involving 77 Year 1 and 81 Year 2 IIUM medical students to answer a self-administered online survey. We used the Abbreviated World Health Organisation Quality of Life (WHOQOL-BREF) questionnaire to assess the students’ quality of life. We analysed the data using IBM SPSS Statistics 26 (IBM, New York). This study lasted from July till August 2021 under the approval of the institutional research committee (Research ID: 735). From this study, the mean score for overall quality of life was 14.58 (3.23), with no significant difference between Year 1 and Year 2 students (p=0.216). The average score across all four domains ranged between 12.19 (2.53) and 15.3 (2.43), indicating that they had a positive outlook on their well-being. Psychological health scored the lowest whereas environmental health was the highest. Looking into the individual items, the ability to concentrate scored the lowest [10.68 (2.73)]. We concluded that IIUM medical students reported good quality of life even at the height of the pandemic. This finding is likely due to the practice of adequate coping skills among the students to survive learning under lockdown. Nevertheless, we should pay due attention to some parameters, especially their psychological health i.e., focus and concentration, and intervene early to prevent further decline in quality of life

On March 11, 2020, World Health Organization (WHO) declared that COVID-19 has become a pandemic. Therefore, online learning (OL) has replaced face-to-face teaching and learning sessions in many schools and colleges. This has forced the students to adapt to a new environment and overcome some barriers during the OL. However, the increase in suicidal rate among students is a disturbing phenomenon due to mental vulnerability experienced during the current worldwide situation. This study was done to investigate the association between barriers of learning during Covid-19 with mental well-being among International Islamic University Malaysia (IIUM) pre-clinical medical students. A cross-sectional study was conducted among the Year 1 (n=77) and Year 2 (n=81) medical students of IIUM, from July until August 2021. They were recruited to answer self-administered online questionnaires based on 5 remote learning barriers (inadequate interaction with classmates and teachers, lack of peer support and confidence to handle online tasks, and difficulty in applying taught concepts). The survey includes Generalised Anxiety Disorder (GAD-5) and Well Being Index (WHO5) to assess mental well-being and was approved by the institutional ethical committee (Research ID: 735). The results were analysed using IBM SPSS Statistics 26 (IBM, New York). The prevalence of depression and anxiety among medical students were 27.8% and 86.7% respectively. More than half of the respondents agreed with all learning barriers listed. However, the difficulty in applying taught concepts is the only significant barrier associated with depression (p<0.05). In conclusion, although only one item was identified as significant, it was an undeniable factor. Corrective measures must be taken to minimize it as continuous exposure may deteriorate mental health among medical students. Careful evaluation is required in order to ensure the quality of education remains upheld to its highest standards without jeopardizing the students’ psychological well-being

Soluble protein can be extracted if muscle fibres are lysed and the extractability depends on several factors such as choice of buffer, presence of protein inhibitor and the osmolarity of the resuspension buffer (1). Proteins can be severely affected by small changes in hydrogen ion concentration. Some proteins tend to precipitate when the pH approaches their isoelectric point (pI) (7). Therefore, in order to ensure reproducible results, it is important to maintain the protein solution at the constant pH. Once an optimal pH has been determined, different buffer within the same pH range may also be examined for specific buffer effects (2). Different types of skeletal muscles are composed of different proportion of fibers at which the differences influence the metabolic capability (4, 6). Differences in rate of post-mortem glycolysis could induce changes in protein solubility (3). In addition, the selection of the ST, LD and SS muscles for the study was based on their previously reported metabolite and contractile characteristic as well as fiber type composition (5). The aim of this study was to evaluate the effects of the type, pH and molarity of extraction buffer on protein extractability from beef Semitendinosus (ST) Longissimus dorsi (LD) and Supraspinatus (SS) muscles.

Due to the COVID-19 pandemic, several preventive measures have been put in place including movement restriction and closure of non-essential services in Malaysia including educational premises and shifting towards online learning. Physical inactivity may impact medical students’ quality of life, particularly their physical and mental health, as both are especially influenced by doing physical activity. This study aimed to assess the physical health of medical students during the pandemic. This study has been approved by the institutional research committee (Research ID: 735). All Year 1 and Year 2 International Islamic University Malaysia (IIUM) medical students were invited to participate in this cross-sectional study. Participants were asked to complete an online, self-administered abbreviated World Health Organisation Quality of Life (WHOQOL-BREF) questionnaire from July until August 2021. Data were analysed using IBM SPSS Statistics 26 (IBM, New York). We received 158 responses, consisting of 77 Year 1 and 81 Year 2 students. All participants were undertaking online remote learning at the time of study. The mean score for overall quality of life was 14.58 (3.23) whereas the physical health domain mean score was 14.18 (2.48). We found that the requirement for medical treatment scored the highest 17.70 (3.42) whereas work capacity scored the lowest 12.25 (3.95). There was no significant difference in the scores between 14.50 (2.56) and 13.87 (2.37) for Year 1 and Year 2 students in the individual items (p=0.107- 0.862). We concluded that despite the nationwide lockdown, the medical students in IIUM reported acceptable-good quality of life and physical health. This could be due to their adaptation to the new norms by applying the right coping strategy. Future study to re-assess their quality of life is due should the lockdown are further extended or tightened

This study aimed at assessing the climatic temperature and precipitation across agroecological zones during cropping seasons. Moreover, climatic variations in Pakistan for both parameters were gauged across defined Agroecological zones comprising both cropping seasons traditionally known as Rabi (Winter/Wheat growing) and Kharif (Autumn/Rice growing). Targeting comprehensive analysis, each season further disintegrated in the three stages i.e. sowing, flowering and harvesting stages. We incorporated meteorological data from 1961 to 2017, further climatic parameters extracted by employing a 30-years moving average of monthly means. The study revealed that the three zones having rugged topography were highly vulnerable during Rabi (Winter/Wheat growing) Season having +0.5oC variation in climatic temperature, whereas more than 20mm steep rise in climatic precipitation, it may cause increased or frequent flooding in lower plains. While the zones having smooth and plane topography are muc...

Introduction: Young onset psychosis has poor prognosis, and inborn errors of metabolism (IEM) can be easily missed. There is scarce information regarding IEM and young onset psychosis in Malaysia. Case Report: A 15-year-old Malay girl presented at the age of 8 years with a history of intellectual disability and neuro-regression, subsequently developing psychotic and obsessive-compulsive symptoms several years later. Organic workup revealed elevated lactate levels. Urine organic acid chromatogram revealed a moderate peak of lactate however most other investigations were normal. As MRI brain is normal and there are no neurological signs it appears less likely there is an underlying IEM-related aetiology for psychosis. Discussion: Various IEMs can be related to psychosis however the incidence is very low and quality of evidence is poor. Thus, any psychiatric presentation, particularly with suggestive clinical signs, should warrant an organic (including IEM) workup since these causes ar...

Identifying general surgical patients at risk of poor outcome can be a diagnostic challenge. This study aimed to determine the significance of admission serum acute phase reactants in predicting emergency general surgical outcome. An electronic database containing all acute general surgical admissions over two years was analysed to correlate admission acute phase reactants (including C-reactive protein (CRP), absolute neutrophil count (ANC) and serum albumin) with outcome. Study endpoints included: cross-sectional imaging, surgery, intensive care admission, in-hospital mortality and length-of-stay (LOS). A total of 9738 patients were enrolled in the study. Elevated CRP (n= 4635; 47%) was associated with: advanced imaging 17% vs 30% (p=0.0001), surgery 15% vs 28% (p=0.0001), ITU admission 3% vs 7% (p=0.0001) and mortality 0.5% vs 2% (p=0.0001). A cut-off level of >150 mg/L was most significant. Abnormal ANC (n= 4104; 42%) was significant in predicting advanced imaging 15% vs 55% (...

GDSL-type esterase/lipase (GELP) is mainly characterized by a conserved GDSL domain at N terminus, and is widely found in all living species, both prokaryotes and eukaryotes. GELP gene family consists of a wide range of members playing important roles in plant physiological processes, such as development, stress responses, and functional divergences. In our study, 597 GELP genes were identified from six Rosaceae genomes (i.e., Fragaria vesca, Prunus persica, Prunus avium, Prunus mume, Pyrus bretschneideri, and Malus domestica) by a comprehensive analysis. All GELP genes were further divided into ten subfamilies based on phylogenetic tree analysis. Subfamily D and subfamily E are the two largest subfamilies. Microcollinearity analysis suggested that WGD/segmental events contribute to the expansion of the GELP gene family in M. domestica and P. bretschneideri compared to F. vesca, P. persica, P. avium, and P. mume. Some PbGELPs were expressed during the fruit development of P. bretsch...

Natural products with therapeutic nature are nowadays warmly welcomed in textiles. Current study is concerned with isolation of tannin from neem bark (Azadirachta indica) and its application onto silk fabric. For improvement in shades, chemical & bio-mordants have been employed at optimal dyeing conditions. It is found that methanolic extract of pH 5 obtained 8 g dye powder after US Treatment for 30 min has given high color strength if used to dye irradiated silk for 65 min at 75 °C. Bio-mordanting using herbal plants has improved the color characteristics as compared to chemical mordants used. ISO standards for color fastness reveal that herbal based bio-mordants have improved the rating from good to excellent as compared to chemical mordants used. It is concluded that US treatment has not only isolate the colorant for neem bark under mild condition but also given excellent characteristic using bio mordants onto silk fabrics.

SWEET genes are a recently identified plant gene family that play an indispensable role in sugar efflux. However, no systematic study has been performed in pear. In this research, 18 SWEET transporters identified in pear, almost twice the number found in woodland strawberry and Japanese apricot, were divided into four clades. Conserved motifs and six exons of the SWEET transporters were found in six species. SWEET transporters contained seven transmembrane segments (TMSs) that evolved from an internal duplication of an ancestral three-TMSs unit, connected by TMS4. This is the first direct evidence identifying internal repeats through bioinformatics analysis. Whole-genome duplication (WGD) or segmental duplication and dispersed duplication represent the main driving forces for SWEET family evolution in six species, with former duplications more important in pear. Gene expression results suggested that PbSWEET15 and PbSWEET17 have no expression in any tissues because of critical lost ...
