Tinjauan Biografi-bibliografi Ibn Al-haytham

Ibn al-Haytham (w. 1038/9 M) lebih dikenal sebagai seorang saintis dan ahli matematika hingga saat ini. Kajian ini bertujuan untuk meninjau kembali posisinya diantara sarjana muslim melalui penyelidikan dan peninjauan lebih seksama terhadap sumber-sumber riwayat hidupnya dan karya-karyanya, untuk memperoleh gambaran yang lebih sesuai. Kaidah yang digunakan dalam penelitian ini adalah kaidah sejarah khususnya penyelidikan bio-bibliografi. Hasilnya, meskipun Ibn al-Haytham merupakan tokoh yang menonjol dalam sains dan matematika, tetapi sebenarnya Ibn al-Haytham merupakan seorang filsuf muslim yang menghasilkan karya dalam spektrum bidang keilmuan beragam. Satu-satunya karya yang banyak membahas segi filsafat ternyata masih dapat diperoleh saat ini yaitu Kitāb Thamarah al-Ḥikmah, yang memperkuat bukti bahwa ia bukan saja seorang saintis dan ahli matematika tetapi juga seorang filsuf muslim

Synthesis and Characterization of 2-Ethoxy Isobutryl Acid Hydrazide and 2-Ethoxy Isobutryl Aceto Hydrazone and Its Metal Complexes with Co(II), Ni(II) and Cu(II)

Complexes of Co(II), Ni(II) and Cu(II) derived from 2-ethoxy isobutryl acid hydrazide (EIAH1) and 2-ethoxy isobutryl aceto hydrazone (EIAH2) have been synthesized and characterized by elemental analysis, FT-IR, molar conductance, UV – visible spectra, ESR, thermal analysis and magnetic susceptibility. The complexes are coloured, stable in air and exhibit coordination number of 4 or 6. Analytical data showed that all the complexes exhibited 1:2 (metal:ligand) ratio. The changes observed between the FT-IR and UV – visible spectra of the ligands and of the complexes allowed us to establish the coordination mode of the metal in complexes. Presence of coordinated water molecules in Co (II) and Ni (II) complexes is confirmed by TGA studies. The conductivity data show that all these complexes are non electrolytes. The solubility test on the ligands and its metal(II) complexes revealed their solubility in dimethylsulphoxide (DMSO). The ligands and metal complexes show a good activity against the bacteria; B. Subtilis, E.coli and S.aureus and fungi A.niger, A.flavus and C.albicans. The antimicrobial results also indicate that the metal complexes are better antimicrobial agents as compared to the ligands.

Covid-19 pandemic impact on colonoscopy service and suggestions for managing recovery

Abstract Background and aim As the post-peak phase of the epidemic is approaching, there is an urgent need of an action plan to help resume endoscopy activity. To manage the Covid-19 pandemic-imposed backlog of postponed colonoscopy examinations, an efficient approach is needed. The practice of on-demand sedation with benzodiazepines and/or opiates will allow most patients to complete a water-aided examination with minimal or no sedation. Other methods reported to minimize patient discomfort during colonoscopy can be used, in addition to water-aided techniques. Unsedated or minimally sedated patients who do not require recovery or require a shorter one allow rapid turnaround. The practice obviates the need for assistance with deep sedation from anesthesiologists, who may be in short supply. Trainee education in water-aided colonoscopy has been demonstrated to confer benefits. This review provides some insights into the impact of Covid-19 on endoscopy services, challenges ahead, and possible solutions to help recovery of colonoscopy work and training

Self-compacting geopolymer concrete with spend garnet as sand replacement

Garnets being the waste spin-off of surface treatment operations remain a major environmental concern worldwide. Robust engineering properties of these waste garnets offer the opportunity to get efficient construction materials via their appropriate recycling. In this spirit, we evaluate the capacity of spent garnets as sand replacement for achieving self-compacting geopolymer concrete (SCGPC). Such SCGPC specimens are prepared using ground granulated blast furnace slag (GGBFS) wherein the river sand is replaced by spent garnet at varying contents (0–100%) under constant Liquid/Binder (L/B) mass ratio of 0.4. Performance evaluations of the developed SCGPC samples are made using several tests including durability, workability, flexural, compressive, splitting tensile strength conforming the EFNARC standard. Test results revealed an enhancement in the workability of the proposed SCGPC specimen with the increase of spent garnet contents. Furthermore, other strengths are discerned to be lower compared to the control sample at all stages of replacement. It is established that the spent garnet is prospective candidate for sand replacement up to 25% in terms of environmental amiability, cost effectiveness and conservation of natural resources

Gender-based differences of inflammatory, coagulation, and cardiac markers in COVID-19 patients in Erbil city

In December 2019, a new coronavirus disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) appeared in Wuhan city and quickly became a global health issue. COVID-19 causes various symptoms ranging from no symptoms to potentially deadly pneumonia. The study aimed to understand the effects of SARS-CoV-2 infection on immune response and the differences in inflammatory, coagulation, and cardiac biomarkers between male and female patients. Between June 1st and November 1st, 2020, 95 cases of SARS-CoV-2 infected individuals were studied at Zanko Hospital. SARS-CoV-2 infection was confirmed using the real-time RT-PCR technique. All cases were analyzed for clinical, epidemiological, and laboratory data. On average, the patients were 50.64 (SEM= 2.359) years old, with 61 males and 34 females. The patients had elevated C-reactive protein (CRP), which was 43.96 (SEM= 6.154), while the erythrocyte sedimentation rate (ESR) was 50.50 (SEM= 5.498). The mean of D-Dimer, ferritin and lactate dehydrogenase (LDH) were 1.204 (SEM= 0.164), 534.7 (SEM= 61.48), and 366.6 (SEM= 36.81), respectively. There were no significant differences in the study's data mentioned above between male and female patients. In conclusion, inflammation is the most prominent symptom in COVID-19 patients, and males and females are nearly equally affected

Accumulation of copy number alterations and clinical progression across advanced prostate cancer

Background: Genomic copy number alterations commonly occur in prostate cancer and are one measure of genomic instability. The clinical implication of copy number change in advanced prostate cancer, which defines a wide spectrum of disease from high-risk localised to metastatic, is unknown. Methods: We performed copy number profiling on 688 tumour regions from 300 patients, who presented with advanced prostate cancer prior to the start of long-term androgen deprivation therapy (ADT), in the control arm of the prospective randomised STAMPEDE trial. Patients were categorised into metastatic states as follows; high-risk non-metastatic with or without local lymph node involvement, or metastatic low/high volume. We followed up patients for a median of 7 years. Univariable and multivariable Cox survival models were fitted to estimate the association between the burden of copy number alteration as a continuous variable and the hazard of death or disease progression. Results: The burden of copy number alterations positively associated with radiologically evident distant metastases at diagnosis (P=0.00006) and showed a non-linear relationship with clinical outcome on univariable and multivariable analysis, characterised by a sharp increase in the relative risk of progression (P=0.003) and death (P=0.045) for each unit increase, stabilising into more modest increases with higher copy number burdens. This association between copy number burden and outcome was similar in each metastatic state. Copy number loss occurred significantly more frequently than gain at the lowest copy number burden quartile (q=4.1 × 10−6). Loss of segments in chromosome 5q21-22 and gains at 8q21-24, respectively including CHD1 and cMYC occurred more frequently in cases with higher copy number alteration (for either region: Kolmogorov–Smirnov distance, 0.5; adjusted P<0.0001). Copy number alterations showed variability across tumour regions in the same prostate. This variance associated with increased risk of distant metastases (Kruskal-Wallis test P=0.037). Conclusions: Copy number alteration in advanced prostate cancer associates with increased risk of metastases at diagnosis. Accumulation of a limited number of copy number alterations associates with most of the increased risk of disease progression and death. The increased likelihood of involvement of specific segments in high copy number alteration burden cancers may suggest an order underlying the accumulation of copy number changes

Physical activity, smoking, and genetic predisposition to obesity in people from Pakistan:the PROMIS study

Background: Multiple genetic variants have been reliably associated with obesity-related traits in Europeans, but little is known about their associations and interactions with lifestyle factors in South Asians. Methods: In 16,157 Pakistani adults (8232 controls; 7925 diagnosed with myocardial infarction [MI]) enrolled in the PROMIS Study, we tested whether: a) BMI-associated loci, individually or in aggregate (as a genetic risk score - GRS), are associated with BMI; b) physical activity and smoking modify the association of these loci with BMI. Analyses were adjusted for age, age(2), sex, MI (yes/no), and population substructure. Results: Of 95 SNPs studied here, 73 showed directionally consistent effects on BMI as reported in Europeans. Each additional BMI-raising allele of the GRS was associated with 0.04 (SE = 0.01) kg/m(2) higher BMI (P = 4.5 x 10(-14)). We observed nominal evidence of interactions of CLIP1 rs11583200 (P-interaction = 0.014), CADM2 rs13078960 (P-interaction = 0.037) and GALNT10 rs7715256 (P-interaction = 0.048) with physical activity, and PTBP2 rs11165643 (P-interaction = 0.045), HIP1 rs1167827 (P-interaction = 0.015), C6orf106 rs205262 (P-interaction = 0.032) and GRID1 rs7899106 (P-interaction = 0.043) with smoking on BMI. Conclusions: Most BMI-associated loci have directionally consistent effects on BMI in Pakistanis and Europeans. There were suggestive interactions of established BMI-related SNPs with smoking or physical activity
