Characterization and In Silico Analysis of Pregnancy-Associated Glycoprotein-1 Gene of Buffalo (Bubalus bubalis)
Pregnancy-Associated Glycoproteins (PAGs) are trophoblastic proteins belonging to the Aspartic proteinase family secreted by different placental cells of many mammalian species. They play a pivotal role in placentogenesis, foetomaternal unit remodeling, and implantation. The identification of the genes encoding those proteins will be helpful to unravel the intricate embryogenomic functions during pregnancy establishment. Considering importance of these proteins, the present study was undertaken to characterize the pregnancy associated glycoprotein-1 gene of buffalo. An 1181 base pairs buffalo Pregnancy-Associated Glycoprotein PAG-1 gene was PCR amplified from the RNA obtained from the fetal cotyledons. BLAST analysis of the buffalo PAG-1 sequence retrieved a total of 20 cattle, 5 goat, and 4 sheep PAG sequences, exhibiting more than 80% similarity. Buffalo PAG-1 gene contained an uninterrupted open reading frame of 1140 base pairs encoding 380 amino acids that possess a 15 amino acid signal peptide and mature peptide of 365 amino acids. The phylogenetic study of the buffalo PAG-1 gene revealed buffalo PAG-1 is more related to cattle, goat, and sheep PAG-1 sequences. By this study characterization of buffalo PAG-1 gene and its evolutionary relationship was deduced for the first time
Data sharing governance in sub-Saharan Africa during public health emergencies:gaps and guidance
While the COVID-19 pandemic has captured the attention of the global community since the end of 2019, deadly health pandemics are not new to Africa. Tuberculosis (TB), malaria and human immunodeficiency virus (HIV) count amongst other serious diseases that have had a catastrophic impact on the African continent. Effective responses to such pandemics require high-quality, comprehensive data sets that can inform policymaking and enhance healthcare decision-making. While data is driving the information economy in the 21st century, the scarcity in Africa of carefully curated, large epidemiologic data sources and analytical capacity to rapidly identify and understand emerging infectious diseases poses a major challenge to mounting a time-sensitive response to unfolding pandemics. Data access, sharing and transfer between countries are crucial to effectively managing current and future health pandemics. Data access and sharing, however, raises questions about personal privacy, the adequacy of governance mechanisms to regulate cross-border data flows, and ethical issues relating to the collection and use of personal data in the interests of public health. Sub-Saharan Africa’s most research-intensive countries are characterised by diverse data management and privacy governance frameworks. Such regional variance can impede time-sensitive data sharing and highlights the need for urgent governance reforms to facilitate effective decision-making in response to rapidly evolving public health threats.</p
Marine seismic surveys for hydrocarbon exploration: What’s at stake?
With a coastline extending approximately 3900 km, South Africa exercises jurisdiction over a vast Exclusive
Economic Zone (EEZ) that exceeds 1.5 million km2
.

South Africa is located at an ecologically important crossroad
for inter-ocean exchange of heat, salt and biota2
involving the warm, fast-flowing Agulhas current of the Indian
Ocean and the cold, nutrient-rich Benguela upwellings of the Atlantic Ocean, and within the range of influence
of the world’s most biologically productive ocean3
, the Southern Ocean4-6. South Africa’s marine territory is
also characterised by spectacular topography, including dramatic canyons, slopes, plateaus, and seamounts.7
Unsurprisingly, South Africa’s complex oceanographic influences, coastal topography, and geology boasts 179
marine ecosystem types, with 150 around South Africa and 29 in the country’s sub-Antarctic territory.8 South
Africa may also be richly endowed with hydrocarbon deposits.9,10 Seismic surveys are a routine and key upstream
component of the hydrocarbon sector and crucial to understanding where recoverable oil and gas resources
likely exist. Hydrocarbon extraction is largely dependent on seismic data acquisition and processing technology,
with exploration companies relying on seismic survey results to decide whether or where to extract hydrocarbon
deposits. While seismic surveys pose an immediate threat to South Africa’s exceptionally rich marine life, the
downstream implications of such surveys – the extraction and use of non-renewable energy sources – are more
profound

Shared Principles of Ethics for Infant and Young Child Nutrition in the Developing World
Abstract
Background
The defining event in the area of infant feeding is the aggressive marketing of infant formula in the developing world by transnational companies in the 1970s. This practice shattered the trust of the global health community in the private sector, culminated in a global boycott of Nestle products and has extended to distrust of all commercial efforts to improve infant and young child nutrition. The lack of trust is a key barrier along the critical path to optimal infant and young child nutrition in the developing world.
Discussion
To begin to bridge this gap in trust, we developed a set of shared principles based on the following ideals: Integrity; Solidarity; Justice; Equality; Partnership, cooperation, coordination, and communication; Responsible Activity; Sustainability; Transparency; Private enterprise and scale-up; and Fair trading and consumer choice. We hope these principles can serve as a platform on which various parties in the in the infant and young child nutrition arena, can begin a process of authentic trust-building that will ultimately result in coordinated efforts amongst parties.
Summary
A set of shared principles of ethics for infant and young child nutrition in the developing world could catalyze the scale-up of low cost, high quality, complementary foods for infants and young children, and eventually contribute to the eradication of infant and child malnutrition in the developing world
