Gut content analysis is a useful tool when studying arthropod predator-prey interactions. We used polymerase chain reaction （PCR） technique to examine how detection of prey DNA in the gut content of predators was influenced by digestion time and temperature. Such knowledge is critical before applying PCR-based gut content analysis to field collected predators. Larvae of the two-spotted ladybeetle （Adalia bipunctata L.） were fed with the bird cherry-oat aphid （Rhopalosiphum padi L.） at either 21℃ or 14℃. After consuming one aphid, the predators were allowed to digest the prey for a range of time periods up to 24 hours. The influence of temperature on A. bipunctata feeding behavior was also recorded. From the fed larvae, total DNA was extracted and PCR reactions with R. padi specific primers were run. The number ofA. bipunctata that tested positive for R. padi DNA was negatively related to the length of digestion time. Temperature influenced larval feeding behavior but did not have a significant effect on R. padi DNA detection. After pooling the data from both temperature treatments we estimated the time point when R. padi DNA could be amplified from 50% of the fed A. bipunctata by PCR to be 4.87 hours. With such a rapid decrease in prey DNA detection success, positive PCR reactions will most likely be the result of predation events occurring shortly before capture. If a defined digestion temperature range has proven not to influence prey detection, PCR data obtained from predators collected within that particular range can be interpreted in the same way.

作者： Yury Karpechko anna Karpechko Andrej Tuyunen Forest Research Institute of the Karelian Research Centre of the Russian Academy of Sciences 11 Pushkinskaya St.PetrozavodskKareliaRussia 185910

This article examines the physiological relationships between fine roots and foliage, and how their biomass ratio correlates with changes in stand quality class. The biomass of fine roots ≤ 3 mm in diameter of spruce stands in the Republic of Karelia (Northwest Russia) was determined by the soil monolith method. Foliage biomass was calculated using a previously designed technique from the standing stock, average height and quality class of the stand. A relation between fine-root: foliage biomass ratio and stand quality class (representing soil fertility) has been established. The closest correlation between fine-root: foliage biomass ratio and stand quality based on soil fertility was for the 1-2 mm root fraction. Analysis of the water flux balance in the trees revealed a correlation between fine-root: foliage ratio and the ratio of the specific volume of transpiration by the stand to the specific volume of water uptake from the soil by roots. Theoretical explanations for the decrease in fine-root: foliage biomass ratios with increasing stand quality class are offered.

目的比较观察新鲜瘤块及不同时间低温冻存VX2肝癌瘤块经复苏后构建兔肝癌模型的效果。方法选取鱼肉状新鲜VX2瘤块,剔除周边坏死组织和肌肉后,-80℃下冰冻3、5和7个月。20只新西兰大白兔随机分为4组,A组予新鲜瘤块肝脏原位种植法构建VX2兔肝癌模型;B、C、D组分别给予-80℃冰冻3、5和7个月的瘤块,复苏后采用肝脏原位种植法构建兔肝癌模型。14 d后观察各组瘤兔肝脏的成瘤效果。通过免疫荧光观察肿瘤的增殖、凋亡及新生血管。结果A、B、C、D 4组的成瘤率为100%,但随着冻存时间的延长,5个月以后的瘤块活性差异性变大,肝脏肿瘤中心坏死面积增加。组织学检查发现,A、B两组模型TUNEL、Ki67、HIF1-α、VEGF、CD31表达无明显差异,而A、B组与C、D组相比,TUNEL、Ki67、HIF1-α、VEGF、CD31表达差异显著。结论-80℃下离体低温储存瘤块构建的兔VX2肝癌模型7个月内均可成瘤,5个月后瘤块间活性差异性变大,但整体来看可较好地保存瘤株活性,节省人力物力。

Introduction: Type 1 diabetes can have acute complications, sometimes requiring hospitalization. The aim of this study was to describe the epidemiological, clinical and evolutionary aspects of type 1 diabetes in patients at the Abass Ndao National Hospital in Dakar. Patients and Methods: This was a cross-sectional, descriptive and analytical study conducted from January 01, 2010 to December 31, 2021. It focused on hospitalized type 1 diabetic patients. Epidemiological, clinical and evolutionary data were evaluated. Results: Six hundred and fifty-nine (659) patients were enrolled, representing a frequency of 11.5%. The mean age was 29.47 years, giving a sex ratio (m/f) of 0.95. Average hospital stay was 6.1 days. One hundred and forty-four (144) patients (21.8%) had inaugural diabetes. The average consultation time was 14.89 days. Acute metabolic complications were ketoacidosis in 353 patients (56%), and hypoglycemia in 1.2%. Simple hyperglycemia was noted in 113 patients (18.0%). Infection was present in 522 patients (58.3%), of whom 95 (28.2%) had a skin infection.55 patients (16.3%) had a respiratory infection. 12.3% had a dietary imbalance.176 cases (27.7%) had no imbalance.26 patients (3.9%) died, with infectious pathologies accounting for the majority of decompensation factors among the deceased (57.7%). Conclusion: Type 1 diabetes is a cause of morbidity and mortality. It is essential to develop and implement a prevention and management program.

Introduction: Obesity and overweight are a public health problem. The general objective was to determine the epidemiological aspects of obesity, overweight and associated risk factors in a semi-urban environment. Patients and Methods: This was a cross-sectional, descriptive study conducted on November 28 and 29, 2023 in Sébikotane. It focused on volunteers for screening for chronic non-communicable diseases. Epidemiological and clinical data were evaluated. Results: One hundred and twenty-nine cases of obesity were recorded (28%). Two hundred and eighty-two cases were overweight or obese (61.3%). The mean age was 49.55 years, with a standard deviation of 12.41 years. The age group [40 - 49 years] was the most representative, with 85 cases (30.1%), and the majority were female, with 264 cases (93.6%). Primary education was the most common, with 75 cases (46.3%). Grade 1 obesity concerned ninety-seven cases (75.2%), and diabetes was present in thirty cases (23%). Hypertension was present in ninety-five cases (33.7%). Obesity was more marked in the age group [40 - 49 years] with 45 cases (36%). Conclusion: Obesity and overweight are a major cause of morbidity and mortality. The development and implementation of a prevention and management program is essential.
