Grimal, A., H. M. Safaa, and G. M. K. Mehaisen, "{PHYLOGENETIC RELATIONSHIP AMONG FOUR EGYPTIAN AND ONE SPANISH RABBIT POPULATIONS BASED ON}", 10 th World Rabbit Congress, pp. 177–181, 2012. Abstract2012_g33_josevicente.pdf

Seventeen microsatellite loci were used to identify the phylogenetic relationship among four Egyptian breeds and one Spanish line of rabbits. A total of 114 bucks rabbits belonging to four Egyptian breeds -Black Baladi (EBB), Gabali (EG), Red Baladi (ERB) and White Giza (EWG)- and Spanish White New Zealand line from Universidad Politécnica de Valencia (NZW) were studied. All microsatellite loci typed were polymorphic. The average number of alleles per locus was 5.41, ranging from 2 to 12. A total of 16 private alleles were found in 7 out of 17 microsatellite loci used. Mean observed heterozygosity was 0.527, ranging from 0.477 in the NZW breed to 0.581 in the EWG. Lower values for Ho were found for all populations. The inbreeding coefficient of individuals relative to the total population (FIT) was 0.279. The overall within-population heterozygote deficit (FIS) was 0.165, ranging from 0.045 in NZW breed to 0.266 in EBB breed. The overall variation between population (FST) was 0.137, where the NZW breed showed the most differentiated population (FST = 0.194). The Neighbour-Joining tree of the Reynolds genetic distances (DR) among populations shows a clear separation of the Spanish population (NZW) from the Egyptians breeds and there is a population mixture in the Egyptian populations. Only the ERB may to cluster in one independent population.

Hematological malignancies can manifest as extramedullary soft tissue masses in relatively rare cases. The rarity of it causes a diagnostic and therapeutic challenge. One of the rarest manifestations is myeloid sarcoma (MS). MS develops as part of acute myeloid leukemia, myeloproliferative neoplasm, or myelodysplastic syndrome or at relapse, especially following allogeneic hematopoietic stem cell transplant. The tumor displays high myeloperoxidase expression, hence the color green, and is called chloroma. It most commonly appears in lymph nodes, skin and soft tissues, bone, testes, gastrointestinal tract, and peritoneum. Immunohistochemistry shows CD68-KP1 as the most commonly expressed marker, then myeloperoxidase, CD117, CD99, CD68/PG-M1, lysozyme, CD34, terminal deoxynucleotidyl transferase, CD56, CD61, CD30, glycophorin A, and CD4. Different chromosomal abnormalities including MLL rearrangement, t(8; 21), monosomy 7, trisomy 8, trisomy 11, trisomy 4, inversion (16), monosomy 16,16q deletion, 5q deletion, and 20q deletion were reported. Most of the literature about MS are case reports and small retrospective studies, thus there is limited clinical knowledge of the cases and their presentation and management plans. Here, we provide a review of what has been reported in the literature about MS in the light of our experiences.

Goel, A. R., S. S. Chiang, O. Ibrahim, and A. Yalcindag, "{Multisystem Inflammatory Syndrome in an Adolescent Following SARS-CoV-2 Exposure Despite Three Doses of a COVID-19 Vaccine.}", Rhode Island medical journal (2013), vol. 105, no. 5, pp. 41–45, 2022. AbstractWebsite

The multisystem inflammatory syndrome in children (MIS-C) is a known complication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the pediatric population. Recent studies have demonstrated high efficacy of a two-dose vaccine series in preventing MIS-C among adolescents. To date, such studies have only included children exposed to SARS-CoV-2 prior to the emergence of the Omicron variant (B.1.1.529). We report a case of an adolescent who received three doses of a vaccine yet developed MIS-C following known exposure to SARS-CoV-2. Given the uncertainty in whether current vaccines offer as much protection against MIS-C due to the Omicron variant or any potential new variants as they have for older variants, pediatric providers should maintain a high index of suspicion for MIS-C regardless of vaccination status.

Ricci, G. F., A. M. De Girolamo, O. M. M. Abdelwahab, and F. Gentile, "{Identifying sediment source areas in a Mediterranean watershed using the SWAT model}", {LAND DEGRADATION & DEVELOPMENT}, vol. {29}, no. {4}, pp. {1233-1248}, {APR}, 2018. Abstract

{This study aims to evaluate the suitability of the Soil and Water Assessment Tool model in simulating runoff and sediment loss in the Carapelle (SE Italy), a typical Mediterranean watershed, where continuous measurements of streamflow and sediment concentration were collected over a 5-year period, on a half-hour timescale, processed on a daily timescale. After sensitivity analysis, the model was calibrated and validated for runoff and sediment. Statistics show generally satisfactory efficiency. To further improve sediment simulation performance, we used a seasonal calibration scheme, in which data recorded in the dry and wet seasons were used to calibrate sediments separately, on a seasonal basis. We also tested the model's capability in identifying the major sediment source zones and river segments where there is sediment deposition. On the basin scale, the average water yield (186mm) corresponds to 27% of the total rainfall (686mm), and average annual sediment load was estimated to be 6.8tha(-1)year(-1). On the subbasin scale, a gradient of sediment yield was found that is characterised by a large difference among the upper (7 to 13tha(-1)year(-1)), central, and lower parts (<1tha(-1)year(-1)) of the study area. Conversely, deposition in channel flow has its highest values in the central part of the watershed, where there is an alluvial plain. Winter wheat and olive land use are the major source areas, in terms of sediment. This study confirms that the Mediterranean watershed is a fragile ecosystem, and measures are needed to mitigate soil depletion.}

Menjivar, N. G., A. Gad, S. Gebremedhn, S. Ghosh, and D. Tesfaye, "{Granulosa cell-derived extracellular vesicles mitigate the detrimental impact of thermal stress on bovine oocytes and embryos}", Frontiers in Cell and Developmental Biology, vol. 11: Frontiers, pp. 309, apr, 2023. AbstractWebsite

Climate change-induced global warming results in rises in body temperatures above normal physiological levels (hyperthermia) with negative impacts on reproductive function in dairy and beef animals. Extracellular vesicles (EVs), commonly described as nano-sized, lipid-enclosed complexes, harnessed with a plethora of bioactive cargoes (RNAs, proteins, and lipids), are crucial to regulating processes like folliculogenesis and the initiation of different signaling pathways. The beneficial role of follicular fluid-derived EVs in inducing thermotolerance to oocytes during in vitro maturation has been evidenced. Here we aimed to determine the capacity of in vitro cultured granulosa cell-derived EVs (GC-EVs) to modulate bovine oocytes' thermotolerance to heat stress (HS) during in vitro maturation (IVM). Moreover, this study tested the hypothesis that EVs released from thermally stressed GCs (S-EVs) shuttle protective messages to provide protection against subsequent HS in bovine oocytes. For this, sub-populations of GC-EVs were generated from GCs subjected to 38.5°C (N-EVs) or 41°C (S-EVs) and supplemented to cumulus-oocyte complexes (COCs) matured in vitro at the normal physiological body temperature of the cow (38.5°C) or HS (41°C) conditions. Results indicate that S-EVs improve the survival of oocytes by reducing ROS accumulation, improving mitochondrial function, and suppressing the expression of stress-associated genes thereby reducing the severity of HS on oocytes. Moreover, our findings indicate a carryover impact from the addition of GC-EVs during oocyte maturation in the development to the blastocyst stage with enhanced viability.

AbstractWebsite

{End colostomy rates following colorectal resection vary across institutions in high-income settings, being influenced by patient, disease, surgeon and system factors. This study aimed to assess global variation in end colostomy rates after left-sided colorectal resection.This study comprised an analysis of GlobalSurg-1 and -2 international, prospective, observational cohort studies (2014, 2016), including consecutive adult patients undergoing elective or emergency left-sided colorectal resection within discrete 2-week windows. Countries were grouped into high-, middle- and low-income tertiles according to the United Nations Human Development Index (HDI). Factors associated with colostomy formation versus primary anastomosis were explored using a multilevel, multivariable logistic regression model.In total, 1635 patients from 242 hospitals in 57 countries undergoing left-sided colorectal resection were included: 113 (6·9 per cent) from low-HDI, 254 (15·5 per cent) from middle-HDI and 1268 (77·6 per cent) from high-HDI countries. There was a higher proportion of patients with perforated disease (57·5, 40·9 and 35·4 per cent; P \< 0·001) and subsequent use of end colostomy (52·2, 24·8 and 18·9 per cent; P \< 0·001) in low- compared with middle- and high-HDI settings. The association with colostomy use in low-HDI settings persisted (odds ratio (OR) 3·20, 95 per cent c.i. 1·35 to 7·57; P = 0·008) after risk adjustment for malignant disease (OR 2·34, 1·65 to 3·32; P \< 0·001), emergency surgery (OR 4·08, 2·73 to 6·10; P \< 0·001), time to operation at least 48 h (OR 1·99, 1·28 to 3·09; P = 0·002) and disease perforation (OR 4·00, 2·81 to 5·69; P \< 0·001).Global differences existed in the proportion of patients receiving end stomas after left-sided colorectal resection based on income, which went beyond case mix alone.}

Wagdy, "{Gap analysis in the current knowledge limitations in drought assessment research in the eastern Nile River Basin}", International Journal of Engineering Research and Technology, vol. 12, no. 12, pp. 2200–2206, 2019. Abstract17_18881-ijertok2200-2206-revisedbyauthor.pdf

The drought recurrence builds up potential stresses affecting the countries with transboundary river basins. The Nile River is the lifeblood for 11 countries in Africa. In addition, it was and still a point of interest and under extensive researches since early civilization. According to the International Disasters Database (EM-DAT), the Eastern Nile Basin (ENB) suffered from several periods of droughts in the last 30 years that affected millions of lives and led to serious economic, environmental and health impacts. Moreover, the increase in water demand due to population growth and associated development will be most critical in severe drought periods. Therefore, drought monitoring and assessment techniques are crucial to allow mitigation measures to reduce the drought's destructive impacts and losses. This paper assesses the recent researches related to drought occurrence, its extent and distinguishing between types of drought and the commonly used drought indices on the ENB. It is revealed that the drought assessment studies never dealt with the dependency between the sub-catchments of the ENB that have a dynamic regime affected by drought events. In conclusion, the paper identified the gaps in drought assessment research if addressed by researchers, could create substantial leverage on water management under drought conditions.

{G. M. K. Mehaisen, A. Abbas, A. }A. M. H., and A. Galal, "{Effect of linseed oil on egg yolk cholesterol and perfor- mance of laying hens}", Poult. Sci. 90(E-Suppl. 1), vol. 90, pp. 100 (Abstract), 2011. Abstract

This study aimed to investigate the effect of linseed oil as a natural source rich in omega-3 fatty acids on egg yolk cholesterol and per- formance of laying hens. A total of 180 commercial Hy-Line brown laying hens were randomly divided into 4 groups and were fed for 28 d on control diet and diets containing 2, 4 and 6% linseed oil. Egg production performance and feed consumption were recorded during 42 d of the study. Blood and egg samples were collected from laying hens at 14, 28 and 42 d of the experiment to measure the total pro- tein, albumin, globulin, calcium and phosphorus in plasma as well as yolk cholesterol concentration in eggs. Results revealed that egg pro- duction performance was significantly improved by supplementation of linseed oil in the diets (egg number was 39.07 vs. 37.78 eggs/hen and egg mass was 2432.29 vs. 2358.13 g/hen for linseed groups vs. control group, respectively, P < 0.05). Feed consumption was signifi- cantly (P < 0.05) lower in linseed groups than in control group (110.78 vs. 121.05 g/hen/day), and consequently, the feed conversion ratio decreased (2.05 vs. 2.31). Plasma protein, albumin, globulin, calcium and phosphorus were not influenced by the linseed oil levels in the diet. Egg yolk cholesterol significantly decreased by linseed supple- mentation (11.57, 11.18 and 10.98 mg/g cholesterol in 2%, 4% and 6% linseed oil groups vs. 12.80 mg/g cholesterol in control group, P < 0.05). Therefore, the dietary supplementation of linseed oil in chicken diets as natural source of omega-3 fatty acids is healthier for egg con- sumers.
