TL;DR: Foliar Zn fertilization can be realized in combination with commonly-applied pesticides to contribute Zn biofortification of grains in wheat, rice and common bean.
Abstract: Rice (Oryza sativa L.), wheat (Triticum aestivum L.) and common bean (Phaseolus vulgaris L.) are major staple food crops consumed worldwide. Zinc (Zn) deficiency represents a common micronutrient deficiency in human populations, especially in regions of the world where staple food crops are the main source of daily calorie intake. Foliar application of Zn fertilizer has been shown to be effective for enriching food crop grains with Zn to desirable amounts for human nutrition. For promoting adoption of this practice by growers, it is important to know whether foliar Zn fertilizers can be applied along with pesticides to wheat, rice and also common bean grown across different soil and environmental conditions. The feasibility of foliar application of zinc sulphate (ZnSO4.7H2O) to wheat, rice and common bean in combination with commonly used five fungicides and nine insecticides was investigated under field conditions at the 31 sites-years of seven countries, i.e., China, India, Pakistan, Thailand, Turkey, Brazil and Zambia. Significant increases in grain yields were observed with foliar Zn/foliar Zn + pesticide (5.2–7.7 % of wheat and 1.6–4.2 % of rice) over yields with no Zn treatment. In wheat, as average of all experiments, higher grain Zn concentrations were recorded with foliar Zn alone (41.2 mg kg−1) and foliar Zn + pesticide (38.4 mg kg−1) as compared to no Zn treatment (28.0 mg kg−1). Though the magnitude of grain Zn enrichment was lesser in rice than wheat, grain Zn concentrations in brown rice were significantly higher with foliar Zn (24.1 mg kg−1) and foliar Zn + pesticide (23.6 mg kg−1) than with no Zn (19.1 mg kg−1). In case of common bean, grain Zn concentration increased from 68 to 78 mg kg−1 with foliar Zn alone and to 77 mg kg−1 with foliar Zn applied in combination with pesticides. Thus, grain Zn enrichment with foliar Zn, without or with pesticides, was almost similar in all the tested crops. The results obtained at the 31 experimental site-years of seven countries revealed that foliar Zn fertilization can be realized in combination with commonly-applied pesticides to contribute Zn biofortification of grains in wheat, rice and common bean. This agronomic approach represents a useful practice for the farmers to alleviate Zn deficiency problem in human populations.

TL;DR: In this paper, the effects of religious affiliation on sexual initiation and condom use during first sexual experience among young women in Zambia were examined. And the results suggest that affiliation with conservative religious groups is unlikely to reduce the risk of HIV infection, while young women affiliated with conservative groups are more likely to delay sexual initiation but less likely to use condoms during first sex.

TL;DR: In this paper, the authors describe the genomic epidemiology using a dataset of 8746 genomes from 33 African countries and two overseas territories and show that the epidemics in most countries were initiated by importations predominantly from Europe, which diminished following the early introduction of international travel restrictions.
Abstract: The progression of the SARS-CoV-2 pandemic in Africa has so far been heterogeneous and the full impact is not yet well understood. Here, we describe the genomic epidemiology using a dataset of 8746 genomes from 33 African countries and two overseas territories. We show that the epidemics in most countries were initiated by importations predominantly from Europe, which diminished following the early introduction of international travel restrictions. As the pandemic progressed, ongoing transmission in many countries and increasing mobility led to the emergence and spread within the continent of many variants of concern and interest, such as B.1.351, B.1.525, A.23.1 and C.1.1. Although distorted by low sampling numbers and blind spots, the findings highlight that Africa must not be left behind in the global pandemic response, otherwise it could become a source for new variants.

TL;DR: Greater understanding of the influences underpinning societal attitudes towards sexuality and disability in this setting, and more extensive communication between health care staff and women with disabilities would facilitate positive action towards improving safe motherhood and reproductive health services for women with disability are suggested.
Abstract: Purpose: To ascertain how well health services in Lusaka, Zambia currently meet the safe motherhood and reproductive health care needs of women who have physical impairment leading to disability.Methods: A qualitative study was conducted in Lusaka, Zambia. In-depth tape-recorded interviews were conducted with 24 purposively selected women with disabilities and with 25 safe motherhood/reproductive public sector health service providers. Qualitative analysis was conducted using NVivo software.Results: Women with disabilities encounter various social, attitudinal and physical barriers to accessing safe motherhood and reproductive health (RH) services in this particular setting. The strong desire for children and affection can increase vulnerability to sexual exploitation. At the same time, a generalized assumption among reproductive health service providers that women with disabilities will not be sexually active, and not require RH services, leads to increased vulnerability to sexually transmitted infection...

TL;DR: In this paper, the seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem.
Abstract: The seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem. Based on a unique combination of seasonal pan-tropical data sets from 89 experimental sites (68 include aboveground wood productivity measurements and 35 litter productivity measurements), their associated canopy photosynthetic capacity (enhanced vegetation index, EVI) and climate, we ask how carbon assimilation and aboveground allocation are related to climate seasonality in tropical forests and how they interact in the seasonal carbon cycle. We found that canopy photosynthetic capacity seasonality responds positively to precipitation when rainfall is < 2000 mm yr(-1) (water-limited forests) and to radiation otherwise (light-limited forests). On the other hand, independent of climate limitations, wood productivity and litterfall are driven by seasonal variation in precipitation and evapotranspiration, respectively. Consequently, light-limited forests present an asynchronism between canopy photosynthetic capacity and wood productivity. First-order control by precipitation likely indicates a decrease in tropical forest productivity in a drier climate in water-limited forest, and in current light-limited forest with future rainfall < 2000 mm yr(-1).
