Central African Lion
The Central African lion is a Panthera leo leo population in northern parts of Central and East Africa. This population has been fragmented into small and isolated groups since the 1950s. It is threatened by loss of habitat and prey base and trophy hunting. In 2005, a Lion Conservation Strategy was developed for West and Central Africa. Results of phylogeographic research indicate that the Central African lion clade forms a phylogenetic group with lion samples from West and North Africa, the Middle East and India . This group diverged from lions in southern parts of East and Southern Africa at least 50,000 years ago. Morphometric analysis of lion skulls corroborates the assessment of two major evolutionary lion clusters, one in Sub-Saharan Africa and the other in North Africa and Asia.

DENGUE and ZIKA Flaviviruses Nucleic Acid Vaccine
Dengue virus and Zika virus are mosquito-borne, single-stranded, positive-sense RNA viruses that belong to the Flaviviridae family. Both the viruses are closely related and have similarities with other flaviviruses. Dengue virus (DENV) causes a severe febrile illness with fever, joint pain, and rash leading to a life-threatening condition in severe cases. While Zika virus (ZIKV) primarily causes mild fever, it can be passed from a pregnant mother to her fetus, resulting in severe birth defect microcephaly and even causing a rare autoimmune disease—Guillain–Barre syndrome.

Hop
Hops is considered a short-day, temperate species, so the major challenge for the development of hop cultivation in Brazil, with high-yield capacity and with local typicity of bitterness and aroma, is the adaptation of cultivars to the photoperiod conditions in subtropical regions.

Brewer’s Spent Grains
Brewer’s spent grains (BSG) is the main solid by-product in the brewing industry, obtained during lautering. BSG has a multitude of applications and it can be used as a valuable fedstock for production of different products. Moreover, it could also be used as a biomass for energy purposes.

Elicitors in Plants and Insects
Molecular elicitors are the key bio-elements in the detection and recognition of attacking enemies in tissue consumption. Insect oral secretion, frass, and fluid of egg deposition contain biologically active molecules called herbivore-associated elicitors (HAEs) that are recognized by pattern-recognition receptors (PRRs). Many plants distinguish insect feeding from wounding by HAEs present in their oral secretions (OS) and induce local and/or systemic responses against arthropod feeding.

Overview of Dried Fish
Fish is a good source of nutrients, although it is easily spoiled. As such, drying is a common method of preserving fish to compensate for its perishability. Dried fish exists in different cultures with varying types of fish used and drying methods.

Calcium Indicator NCaMP7
Green fluorescent genetically encoded calcium indicators (GECIs) are the most popular tool for visualization of calcium dynamics in vivo. However, most of them are based on the EGFP protein and have similar molecular brightnesses. The NTnC indicator, which is composed of the mNeonGreen fluorescent protein with the insertion of troponin C, has higher brightness as compared to EGFP-based GECIs, but shows a limited inverted response with an ΔF/F of 1. By insertion of a calmodulin/M13-peptide pair into the mNeonGreen protein, we developed a green GECI called NCaMP7. In vitro, NCaMP7 showed positive response with an ΔF/F of 27 and high affinity (Kd of 125 nM) to calcium ions. NCaMP7 demonstrated a 1.7-fold higher brightness and similar calcium-association/dissociation dynamics compared to the standard GCaMP6s GECI in vitro. According to fluorescence recovery after photobleaching (FRAP) experiments, the NCaMP7 design partially prevented interactions of NCaMP7 with the intracellular environment. The NCaMP7 crystal structure was obtained at 1.75Å resolution to uncover the molecular basis of its calcium ions sensitivity.The NCaMP7 indicator retained a high and fast response when expressed in cultured HeLa and neuronal cells. Finally, we successfully utilized the NCaMP7 indicator for in vivo visualization of grating-evoked and place-dependent neuronal activity in the visual cortex and the hippocampus of mice using a two-photon microscope and an NVista miniscope, respectively.

Genomic Aberrations
Multiple Myeloma is a genetically heterogeneous disease, arising and progressing through the appearance and accumulation of a tangle of genomic aberrations. In the last decade, cheap and wide applicable sequencing technologies allowed significant advantages in its biological knowledge. Here author focus on genomic events that drive plasma cell disorders.

Phenolic Compounds in Mulberry
Mulberry, which belongs to the genus Morus of the Moraceae family, is an aggregated berry that is oval-shaped, rich in nutrition, sweet and soft, with a unique flavor. Mulberry is distributed in east, west and southeast Asia, southern Europe, southern North America, northwestern South America and some areas of Africa. There are 24 species of Morus and one subspecies, with at least 100 known varieties.

Bambara Groundnut
Currently, the global agricultural system is focused on a limited number of crop species, thereby presenting a threat to food security and supply, especially with predicted global climate change conditions. The importance of ‘underutilized’ crop species in meeting the world’s demand for food has been duly recognized by research communities, governments and policy makers worldwide. The development of underutilized crops, with their vast genetic resources and beneficial traits, may be a useful step towards solving food security challenges by offering a multifaceted agricultural system that includes additional important food resources. Bambara groundnut is among the beneficial underutilized crop species that may have a positive impact on global food security through organized and well-coordinated multidimensional breeding programs. The excessive degrees of allelic difference in Bambara groundnut germplasm could be exploited in breeding activities to develop new varieties. It is important to match recognized breeding objectives with documented diversity in order to significantly improve breeding.
