Published: November 2022

Abstract
Outside of the polar areas, the Himalayan ranges have far more snow. Approximately 17% of the Himalayas and 37% of the Karakoram Mountains are covered in snow. Fluctuations in glacier advancement or retreat are considered sensitive indicators of climatic variations in the earth system. The present study deals with daily gridded (0.25° x 0.25°) data of extracted variables and investigates the recent trends in temperature and precipitation over severe cold regions of Ladakh, Kargil, and Zaskar. Trends were calculated using parametric (simple linear regression) and non-parametric (Mann- Kendall and Sen’s Slope) tests. Abrupt change point detection in a dataset is also calculated using Pettitt's test and is detected after 2010. The result shows that both rainfall and snowfall show an increasing trend in all the regions but the intensity of the increase is different. It is high over Zaskar at the rate of 5.153 mm/year (rainfall) and 0.702 mm/year (snowfall) at a 99.99% confidence level, while precipitation has also increased throughout the study area. Also, the trend of average temperature shows an increasing trend. This recent shift in climatic trends and patterns could have irreversible implications across the study area, resulting in catastrophic outcomes.

Published: November 2022

Abstract
Background
The number of empty nesters in China is increasing and their health status is poor relative to that of non-empty nesters. However, older adults are not yet aware of the direct and indirect health-promoting effects of social engagement.
Methods
This study used data from the 2018 China Health and Aging Tracking Survey (CHARLS2018) to first conduct a descriptive analysis of the social engagement status and health status of empty nesters, then analyze the effect of social engagement on the health of empty nesters using a multiple regression model, and conduct robustness tests using propensity score matching methods, and then use a mediating effects model to explore the effect of social engagement on Then, we used the mediating effect model to explore the mechanism of social participation on the health of empty nesters, and finally, we used subsample regression to analyze the heterogeneity of different groups of empty nesters.
Results
First, there is a significant effect of social participation on the health status of the empty nesters, and the effects of various types of health still hold after using the propensity score matching method to deal with the endogeneity problem caused by sample selection; Second, economic income and cognitive ability have a significant mediating effect in the process of social participation affecting the health of the empty nesters; Third, there is age, urban and rural heterogeneity in the effect of social participation on the health of the empty nesters heterogeneity, i.e., social participation had a greater impact on the health of urban empty nesters and social participation had the greatest impact on the health of empty nesters aged 70–79.
Conclusions
These results highlight the facilitative effect of social participation on the health status of empty nesters and clarify the mediating role of cognitive ability and economic income in the influence process.
Learning from forest trees: improving urban tree biomass functions
Authors: Vonderach Christian , Akontz Adrienne 
Published: November 2022

Abstract
Trees are one of the few carbon sinks in urban areas. Different methods are available to assess biomass of urban trees, one of it being biomass functions. One advantage of biomass functions is their easy and low-cost application because required data like diameter and height are directly available from tree inventories.
Our data show that it is not suitable to use forest tree biomass functions assize and biomass allocation differ between both ecospheres. Hence, it isimportant to apply specific urban tree biomass function if biomass or carbonstorage is of interest. We started to develop new urban tree aboveground biomass functions using 144 measured deciduous trees of fourteen tree species inKarlsruhe, Germany. Conifers are also of interest but not covered in this data, so we explored several possibilities to build more general models incorporatingdeciduous and conifer tree species from urban and forest origin. Among others, we tested adjusted forest biomass models and a cross-classified mixed model using data from urban and forest origin holding more than 2200 conifer and deciduous trees. This last model shows best predictive performance for deciduous urban tree species, assured by ten-fold cross-validation on group- andpopulation level. We also compared performance to conifer forest biomass functions, showing slightly improved BIAS values. As a feature, the model isalso able to make predictions also for non-observed conifers in urban space, under the assumption of comparable urban-forest differences between deciduousand conifer species. A sample application shows results for a small subset ofdata of a urban tree inventory, collected in a residential area in the city ofMunich, Germany.

Abstract
In dairy, calves are the future replacement stock and need special attention including a good feed management system to attain better conversion efficiency and desired liveweight gains. The Department of Agricultural Research developed a calf starter meal (NEW) from locally available feed resources. The NEW meal was compared with existing meals: SBL and VAN during an on-station trial and, Deo Volente and Derust during an on-farm trial. Thirty-three and 25 pre-weaned Friesian calves with an average initial weight of 38.3 ± 2.5kg and 37.3 ± 1.9kg were randomly allocated to the different diets during the on-station and on-farm trials, respectively. Consumption of the NEW calf meal was significantly (p < 0.05) lower than that of SBL and VAN diets, significantly (p < 0.05) higher than that of Derust diet and comparable to Deo Volente diet (p > 0.05). The feed conversion ratio of the NEW diet was significantly (p < 0.05) lower than diets for the on-station trial and comparable to diets for the on-farm trials (p > 0.05). There was no significant difference (p > 0.05) in body weight gains across the diets. The NEW diet had a lower cost per body weight gain of a calf and a better efficiency of feed utilization compared to all the other diets. The attributes of the NEW diet were rated highly during the on-farm trials. In conclusion, the NEW meal compared relatively well with the other commercial diets used by dairy farmers. The NEW diet is made of locally available resources; cheaper and hence, it can be used to feed dairy calves.

Abstract
Background
Approximately 80% of infected women infected by Chlamydia trachomatis are asymptomatic, although this infection can lead to serious complications in the female reproductive tract. Few data on Chlamydiainfection and genotypes are available in Amazonian communities.
Objectives
To describe the prevalence of and associated factors and to identify the genotypes of sexual C. trachomatis infection in female university students in different urban centers (capital and interiors) in the Brazilian state of Pará, in the eastern Amazon region.
Methods
A cross-sectional study was performed among young women attending public universities in four different urban centers in the eastern Amazon region. They were invited to participate in the studt and cervical secretions were collected for molecular diagnosis of C. trachomatis. We utilized amplification of the ompA gene by nested PCR. Positive samples were genotyped by nucleotide sequencing. Study participants completed a questionnaire on social, epidemiological, and reproductive health variables. A Qui-square and Binominal regression test were used to evaluate the degree of association of these variables with the infection.
Results
A total of 686 female students was included in the study. The overall prevalence of C. trachomatis was 11.2% (77/686). The prevalence of this infection was higher in interiors (15.2% vs 9.5%/ p: 0.0443). Female university students who do not have a sexual partner (11.8%/p <0.008), who do not use a condom in their sexual relations (17.8%/p <0.0001) and who reported having suffered a miscarriage (32%/p <0.0001) have high chances of acquiring this sexual infection. The ompA gene was sequenced in only 33 (42.8%) samples, revealing the genotype J was the most frequent (27.2% [9/33]), followed by genotypes D (24.2% [8/33]), and then genotypes F (18.2% [6/33]), E (15.1% [5/33]) K (6.1% [2/33]), Ia (6.1% [2/33]), and G (3.1% [1/33]).
Conclusions
The high prevalence of sexual infection by C. trachomatis in the female university students from the interior of the state of Pará, individuals with no fixed sexual partner, those that had had a miscarriage, the students that do not use condoms in their sexual relations. The genotype J of C. trachomatis genotypes was the most frequent. These data are important to help defining the epidemiological effects of chlamydial infections in Amazonian populations.
Glyphosate affects persistence and tolerance but not antibiotic resistance
Authors: Ospino Katia , Spira Beny 
Published: November 2022

Abstract
Glyphosate is a herbicide widely used in food production that blocks the synthesis of aromatic amino acids in plants and in microorganisms and also induces the accumulation of the alarmone (p)ppGpp. Resistance, tolerance and persistence to antibiotics are common phenomena that contribute to antibiotic treatment failure. There are several mechanisms through which bacteria attain tolerance or persistence to antibiotics, but all of them involve partial or complete growth inhibition. In this study we evaluated the effect of glyphosate on the resistance, tolerance, and persistence towards the antibiotics ampicillin, ciprofloxacin and kanamycin and the possible role of (p)ppGpp in this activity. Glyphosate did not affect the minimum inhibitory concentration of these antibiotics, but enhanced bacterial tolerance and/or persistence towards them. The upshift in ciprofloxacin and kanamycin tolerance was partially dependent on the presence of relA that promotes (p)ppGpp accumulation in response to glyphosate. Conversely, the strong increase in ampicillin tolerance caused by glyphosate was independent of relA. We conclude that by inducing aromatic amino acid starvation glyphosate contributes to the temporary increase in E. coli tolerance or persistence, but does not affect antibiotic resistance.

Published: November 2022

Abstract
Background
Neer type IIB distal clavicular fractures are inherently unstable as they disrupt the integrity of the conoid ligament. The purpose of this study was to compare the short-term efficacy of TightRope and hook plate in the treatment of distal clavicular fractures.
Methods
A retrospective case control study was conducted to analyze the clinical data of 39 patients with distal clavicular fractures admitted to Sir Run Run Hospital, Nanjing Medical University from January 2018 to June 2022. Clinical and radiological results were assessed using American Shoulder and Elbow Surgeons (ASES) score, Visual Analogue Scale (VAS) and the Constant score.
Results
All patients were followed up for a period of 12 to 24 months, with an average of 16 months. The smaller length of skin incision, less intraoperative blood loss and shorter operative time were detected in the TightRope fixation group than in those of the clavicular hook plate group. (P < 0.01, respectively). Furthermore, the constant score, ASES score and VAS score were significantly improved in the Tightrope technique group than those of the hook plate group (P < 0.01, respectively). No serious postoperative complications such as loosening of internal fixation, loss of reduction or recurrence of fracture were found in either group.
Conclusion
For distal clavicular fractures, TightRope can obtain good clinical outcomes and have obvious advantages in operation time, period for union, lower incidence of shoulder pain and better functional recovery than hook plate.
