Nucleoside Analogs
As the non-naturally occurring biomolecules, modified DNA/RNA nucleoside and oligonucleotide analogues composed of L-(deoxy)riboses, have been designed and applied as innovative therapeutics with superior plasma stability, weakened cytotoxicity, and inexistent immunogenicity.

Hsp70 and Hsp90
Hsp70, Hsp90, and their co-chaperones are crucial members of the proteostasis network that are able to recognize misfolded proteins, aberrant condensates and protein aggregates, triaging proteins for refolding or degradation. These members of the chaperome are considered major sentinels impeding the molecular processes that lead to cell damage in the course of degenerative proteinopathies. Indeed, Hsp70, Hsp90 and their co-chaperones are increasingly recognized as therapeutic targets for the development of treatments against prevalent protein misfolding diseases.

Anticancer Properties of Eugenol
Clove (Syzygium aromaticum L.) (Family Myrtaceae) is a highly prized spice that has been historically utilized as a food preservative and for diverse medical uses. It is reckoned amongst the valued sources of phenolics. Among diverse active components, eugenol, the principal active component of S. aromaticum, has optimistic properties comprising antioxidant, anti-inflammatory, and anticancer actions. Eugenol (4-allyl-2-methoxyphenol) is a musky oil that is mainly obtained from clove. It has long been utilized all over the world as a result of its broad properties like antioxidant, anticancer, anti-inflammatory, and antimicrobial activities. Anticancer effects of eugenol are accomplished by various mechanisms like inducing cell death, cell cycle arrest, inhibition of migration, metastasis, and angiogenesis on several cancer cell lines. Besides, eugenol might be utilized as an adjunct remedy for patients who are treated with conventional chemotherapy. This combination leads to a boosted effectiveness with decreased toxicity.

Hyacinthus orientalis L.
Hyacinthus orientalis L., commonly known as hyacinth, is one of the most important cultivated plants around the world. The cultivars of this species are characterised by their flowers with strong fragrances and a wide range of attractive colours, which make them a beloved option among ornamentals. The chloroplast genomes of Hyacinthus cultivars ranged from 154,458 bp to 154,641 bp, while those of Bellevalia paradoxa and Scilla siberica were 154,020 bp and 154,943 bp, respectively. Each chloroplast genome was annotated with 133 genes, including 87 protein-coding genes, 38 transfer RNA genes and 8 ribosomal RNA genes.

Novel Foods in Madagascar
In Madagascar, the percentage of stunted children under 5 is extremely high. Furthermore, the COVID-19 pandemic is expected to increase the risk of all forms of malnutrition, especially in low-income countries, including Madagascar, with serious intergenerational repercussions.  Efforts to promote native, traditional foods as Moringa oleifera, an indigenous plant in Asia and Africa including Madagascar, rich in protein and micronutrients, as well as edible insects, alternative sustainable source of protein, lipids, iron, and zinc, would provide not only nutritional but also cultural and economic benefits. The potential synergies between food traditions and agroecology have the potential to impact health addressing larger issues of sustainability and food security.

Penguin Visual System
Penguins require vision that is adequate for both subaerial and submarine environments under a wide range of illumination. Amphibious vision is facilitated by a relatively flat cornea, the power in air varying from 10.2 dioptres (D) to 41.3 D depending on the species, and there is good evidence for emmetropia both above and below water. All penguins are trichromats with loss of rhodopsin 2, a nocturnal feature, but only deeper diving penguins have been noted to have pale oil droplets and a preponderance of rods. Conversely, the diurnal, shallow-diving little penguin has a higher ganglion cell density (28,867 cells/mm2) and f-number (3.5) than those that operate in dimmer light. In most species studied, there is some binocular overlap, but this reduces upon submergence.

NMR in Milk Protein Structure
Milk proteins have a complex structure which changes as a result of applied treatment. The newly developed structural conformations of proteins exert influence on the quality of the final product. Structural characterization of milk proteins was successfully performed using NMR. This predominately refers to complete structural assignment on whey proteins and elucidation of sequential fragments of caseins.    As a non destructive method, NMR is a powerful tool which observe the nuclei of atoms immersed in large magnetic field producing radio sensitive signal. The produced signal gives information of the spatial orientation of the molecules and thus tertiary structure of proteins.

Metabolic Disorders and Postpartum Reproduction in Dairy Cows
Early successful conception of postpartum dairy cows is crucial in determining the optimum reproductive efficiency and profitability in modern dairy farming. Due to the inherent high production potential of modern dairy cows, the extra stress burden of peri-parturient events, and associated endocrine and metabolic changes causes negative energy balance (NEBAL) in postpartum cows. The occurrence of NEBAL is associated with excessive fat mobilization in the form of non-esterified fatty acids (NEFAs). The phenomenon of NEFA mobilization furthers with occurrence of ketosis and fatty liver in postpartum dairy cows. High NEFAs and ketones are negatively associated with health and reproductive processes. An additional burden of hypocalcemia, ruminal acidosis, and high protein metabolism in postpartum cows presents further consequences for health and reproductive performance of postpartum dairy cows.

Agroecology-The Case of Cereals
Transformative agroecology has been recognized as a stepping stone to achieving several Sustainable Development Goals (SDGs), due to its great potential to build climate change-resilient farming systems while enhancing ecosystem services and reducing biodiversity loss. Understanding the agroecological elements that underlie the sustainability of an agroecosystem is an urgent matter, serving as the foundation for designing a truly transformative agroecosystem.
