The Modified Double Weighted Exponential Distribution with Properties

The weighted distributions are widely used in many real life fields such as medicine, ecology, reliability, etc., for the development of proper statistical model. The concept of double weighted distribution was introduced by Al-khadim and Hantoosh (2013) and later has been studied by other researchers. In his article,  has been considered as suitable weight for efficient modeling of double weight exponential distribution. The statistical properties of the modified double weighted exponential distribution (MDWED) are explored. The Kolmogorov- Smirnov test has been used to choose a better fitted probability model. The result of this testshown that (MDWED) is more suitable distribution to fit rainfall data then (DWED) proposed by Al-khadim and Hantoosh (2013).

Averrhoa carambola leaves prevent dyslipidemia and oxidative stress in a rat model of poloxamer-407-induced acute hyperlipidemia

Background: The star fruit [Averrhoa carambola L (Oxalidaceae)] is traditionally used in the treatment of many ailments in many countries. It possesses several pharmacological activities, including antioxidant and anti-inflammatory effects. However, it contains the neurotoxic caramboxin and its high content of oxalic acid limits its consumption by individuals with compromised kidney function. This study assessed the anti-hyperlipidemic and antioxidant activities of different fractions of the methanolic extract of A. carambola leaves (MEACL).Methods: The antioxidant activity was investigated using FRAP, and ABTS and DPPH radical-scavenging assays and the inhibitory activity toward pancreatic lipase (PL) and HMG-CoA reductase was assayed in vitro. Acute hyperlipidemia was induced by poloxamer-407 (P-407) in rats and different fractions of MEACL (n-hexane, chloroform, n-butanol, ethyl acetate (EA), water, and chloroform) were orally administered. Cholesterol and triglycerides were determined at 0, 12, 24, and 48 h and LDL-C, vLDL-C, HDL-C, lipid peroxidation (LPO) and antioxidants were assayed after 48 h. The expression of ABCA1, ABCG5, ABCG8, LDL-R, SREBP-1, and SREBP-2 and the activity of HMG-CoA reductase were assayed in the liver of P-407-administered rats treated with the EA fraction.Results: The in vitro data revealed potent radical-scavenging activities of MEACL fractions with the most potent effect showed by the EA fraction that also suppressed the activities of HMG-CoA reductase and PL. In P-407-induced hyperlipidemic rats, all fractions prevented dyslipidemia as shown by the decrease in total cholesterol, triglycerides, LDL-C, vLDL-C and atherogenic index. MEACL and its fractions prevented LPO and boosted GSH, superoxide dismutase, glutathione peroxidase, and catalase in P-407-administered rats. The EA fraction showed more effective anti-hyperlipidemic and antioxidant effects than other fractions and downregulated SREBP-2 while upregulated ABCA1 and LDL-R and ameliorated LPL and HMG-CoA reductase in hyperlipidemic rats.Conclusion: MEACL showed in vitro and in vivo antioxidant activity and the EA fraction significantly ameliorated dyslipidemia in a rat model of P-407-induced acute hyperlipidemia by modulating LPL, PL, HMG-CoA reductase, and cholesterolgenesis-related factors. Therefore, the leaves of A. carambola represent a safe alternative for the star fruit particularly in kidney disease patients, and the EA is the most effective anti-hyperlipidemic and antioxidant fraction

Effects of alginates on the growth, haematological, immunity, antioxidant and pro-inflammatory responses of rabbits under high temperature

Heat stress (HS) is one of the most severe hurdles impacting rabbit growth, immunity, homeostasis, and productivity. Alginate oligosaccharides (AOS) have considerable beneficial effects due to their plausible antioxidant and immune-stimulatory properties. This work was planned to explore the preventive function of AOS as a new bio-feed additive against the harmful effects caused by environmental HS on growing rabbits. Rabbits were allotted in four experimental groups (25 animals in each group) and fed on a basal diet supplemented with 0.0 (AOS0), 50 (AOS50), 100 (AOS100), and 150 (AOS150) mg AOS/kg diet reared under summer conditions. Dietary AOS supplementation improved significantly (P ≤ 0.001) feed conversion rate, while both AOS100 and AOS150 significantly (P ≤ 0.001) enhanced the final body weight and body weight gain. All AOS addition significantly increased nitric oxide and lysosome activity and significantly reduced interferon-gamma (IFNγ) compared with those in the control group. Tumor necrosis factor α (TNFα), interleukin1β (IL-1β), myeloperoxidase and protein carbonyl levels were significantly reduced in rabbits fed diets containing AOS (100 and 150 mg/kg) compared with those in the control group under heat stress conditions. In addition, glutathione (GSH) and catalase (CAT) were significantly (P ≤ 0.001) improved with increasing AOS dietary levels compared with the control group. Still, total antioxidant capacity (TAC), malondialdehyde (MDA), hematocrit, mean corpuscular volume (MCV), eosinophils, and lymphocytes did not change. Erythrocyte's indices improved significantly (P ≤ 0.001), while neutrophils and white blood cell counts were decreased by dietary AOS inclusion. Immunological (IgM and IgG) were markedly reduced in AOS-treated groups compared with the control group. The current investigation exemplified that AOS as a novel bio-feed additive that could be an effective strategy to extenuate prejudicial effects in heat-stressed rabbits via enhancing immunity, and antioxidant defence system, further regulating the inflammation cytokines.Universidad King Saud, Riad, Arabia Saudita | Ref.

Cancer of the breast: 5-year survival in a tertiary hospital in Uganda

The objective was to investigate survival of breast cancer patients at Mulago Hospital. A retrospective study of the medical records of 297 breast cancer patients referred to the combined breast clinic housed in the radiotherapy department between 1996 and 2000 was done. The female/male ratio was 24 : 1. The age range was 22–85 years, with a median of 45 years and peak age group of 30–39 years. Twenty-three percent had early disease (stages 0–IIb) and 26% had metastatic disease. Poorly differentiated was the most common pathological grade (58%) followed by moderately differentiated (33%) and well-differentiated (9%) tumours. The commonest pathological type encountered was ‘not otherwise specified' (76%). Of all patients, 75% had surgery, 76% had radiotherapy, 60% had hormonotherapy and 29% had chemotherapy. Thirty-six (12%) patients received all the four treatment modalities. The 5-year survival probabilities (Kaplan–Meier) for early disease were 74 and 39% for advanced disease (P=0.001). The overall 5-year survival was 56%, which is lower than the rates in the South African blacks (64%) and North American whites (82–88%)

Surat keterangan Syeikh Jalaluddin karangan Fakih Saghir

This critical edition of an early 19th century Malay text consists of five parts: an introduction into the manuscripts and text, a comparison of the two extant manuscripts, a discussion of the language used with particular emphasis on the influence of the Minangkabau dialect, the critical text edition, a concordance correlating manuscript pages with the pages of a printed Malay edition in Jawi, the modified Arabic script used in the Malay World, the facsimile of the main manuscript, a glossary, a bibliography and an index. The text recounts the origins and course of the Padri War in Minangkabau (1825-31) when fanatical converts to Wahabbism tried to force other Muslims to follow their lead. The war only came to an end when the more moderate Wahabbis among the Minangkabau asked for Dutch military assistance against the fundamentalists. The moderates won the war but they had opened the door for colonial rule. This autobiographical account narrates the course of the war through the eyes of its author Syeikh Jalaluddin, the little fakir, who played a full role in the war. It pays particular attention to the efforts of one of the most prominent leaders of the moderate wing, his father. Overall, it is an apologia for the decision to call in the Dutch and, in fact, may have been written with the Dutch in mind

Fortification of conventional Buffalo meat sausage with ash gourd peel enhances shelf life, nutritional, functional and microstructural characteristics

In recent years, food fortification has been seen as one of the important approaches to address nutrients deficiency and also considered as a source of a sustainable form of intervention to reach a wider population. Therefore, the aim of our study was to develop Buffalo meat sausage by incorporating dehydrated ash gourd peel powder (DAGPP). Four sausage formulations were prepared with three levels of DAGPP inclusion (4%, 8%, and 12%) along with a control sample. DAGPP-incorporated sausages were compared with the control sample in terms of scanning electron micrograph (SEM), crude fiber content, antioxidant activity, total phenolic content, and sensory and textural attributes. The storage studies (at 0 °C) were carried out for analysis of physicochemical properties (moisture content, protein content, ash content, pH and TBA value), color parameters (a*, b* and L* values) and microbiological characteristics. Our results showed that crude fiber content and mineral content increased from 0.74% to 6.33% and 1.94% to 2.74%, respectively, on the first day of the study. TBA value decreased from 0.207 to 0.133 (mg of malonaldhyde/ kg sample) on the 14th day of the study. Microbiological analysis revealed that the total plate count, yeast and mold count reduced from 2.87 to 2.12 log cfu/g and 1.93 to 1.38 log cfu/g, respectively, although no coliform was detected. The highest sensory score was achieved for the sample containing 12% DAGPP ie; 7–9. Based upon our findings, we found that the fortified meat sausages had better microstructure and sensory score, increased nutritional value, crude fiber, shelf life as well as high antioxidant activity. Therefore, DAGPP fortified meat sausage can be considered as one of the important sources for proteins and minerals for the under-nutrition population. However, profiling of the fortified food would be warranted to investigate micronutrients along with other functional characteristics
