Difficulties in Kinship Analysis in Armed Conflicts
Regarding human identification in armed conflicts, various complications can be observed. Usually, such difficulties can be social-related, which can include the lack of access to the relative’s genetic material, or the unwillingness of administrative and judicial authorities to participate in the process of identification. In the case of genetics, the analysis allows identifying the individual from a blood sample, a part of an organ, or from skeletal remains, which is why it is considered a much more extensive and effective method when compared with fingerprint techniques or odontology. However, several factors can prevent this identification, such as considerably degraded genetic material. For successful identification, it is mandatory to have access to antemortem biological samples unequivocally attributed to the individual in question, using recombinant nuclear markers, as well as using biological samples from close relatives, whether parents or sons. Nevertheless, the problems associated with armed conflicts make this type of study very difficult.

Animal Model Systems of Parkinson’s Disease
Parkinson's disease is an advancing condition characterized by different types of physical and mental impairments. The characteristic features of Parkinson's disease include the buildup of improperly folded protein known as α-synuclein as Lewy bodies, as well as the deterioration of dopamine-producing neurons in the substantia nigra pars compacta (SNc) region, which impacts the patient's motor functions. Significant studies have been conducted to investigate the use of animal models for Parkinson's disease.

Regulation of Membrane Fluidity in Cold Environments
Temperature changes and periods of detrimental cold occur frequently for many organisms in their natural habitats. Homeothermic animals have evolved metabolic adaptation strategies to increase mitochondrial-based energy expenditure and heat production, largely relying on fat as a fuel source. Alternatively, certain species are able to repress their metabolism during cold periods and enter a state of decreased physiological activity known as torpor. By contrast, poikilotherms, which are unable to maintain their internal temperature, predominantly increase membrane fluidity to diminish cold-related damage from low-temperature stress.

Biogenesis and Expression at PMs of GPI-APs
Glycosylphosphatidylinositol (GPI)-anchored proteins (APs) are produced by coupling of the completed GPI anchor, prefabricated by stepwise transfer from activated precursors of the corresponding carbohydrate and phosphoethanolamine (EtN-P) residues to PI at the luminal face of the ER membranes, to the carboxy-terminus of the polypeptide precursor moiety upon its translation and transient arrest at the endoplasmic reticulum (ER) membranes.

Pharmacological Efficacy of Baicalin in Inflammatory Diseases
Baicalin is one of the most abundant flavonoids found in the dried roots of Scutellaria baicalensis Georgi (SBG) belonging to the genus Scutellaria. Baicalin is demonstrated to have anti-inflammatory, antiviral, antitumor, antibacterial, anticonvulsant, antioxidant, hepatoprotective, and neuroprotective effects.

Mast Cells and Vitamin D Status
The immune system is made up by an extremely composite group of cells, whose regulated and harmonious activity is fundamental to maintain health. The mast cells are an essential effector of inflammatory response which is characterized by a massive release of mediators accumulated in cytoplasmic secretory granules. However, beyond the effects on immune response, mast cells can modify bone metabolism and are capable of intervening in the genesis of pathologies such as osteoporosis and osteopenia. Vitamin D is recognized to induce changes in bone metabolism, but it is also able to influence immune response, suppressing mast cell activation and IgE synthesis from B cells and increasing the number of dendritic cells and IL-10-generating regulatory T cells.

Hearing Loss and Its Pathophysiology
Sensorineural hearing loss is caused by damage to sensory hair cells and/or spiral ganglion neurons. In non-mammalian species, hair cell regeneration after damage is observed, even in adulthood. Although the neonatal mammalian cochlea carries regenerative potential, the adult cochlea cannot regenerate lost hair cells. The survival of supporting cells with regenerative potential after cochlear trauma in adults is promising for promoting hair cell regeneration through therapeutic approaches.

Inhibition of Replication Fork Formation and Progression
Over 1.2 million deaths are attributed to multi-drug-resistant (MDR) bacteria each year. Persistence of MDR bacteria is primarily due to the molecular mechanisms that permit fast replication and rapid evolution. As many pathogens continue to build resistance genes, current antibiotic treatments are being rendered useless and the pool of reliable treatments for many MDR-associated diseases is thus shrinking at an alarming rate. In the development of novel antibiotics, DNA replication initiation and the primosome are still largely underexplored targets.

Marker-Assisted Selection in Breeding for Fruit Trait Improvement
Fruit species breeding takes a lot of effort and time. Trees are probably the worst species to work with in terms of genetics and breeding, with very few exceptions. Large trees, protracted juvenile phases, intensive farming methods, and, despite vegetatively propagation, environmental variability play a significant role in the heritability assessments of each individual important trait. Fruit breeders frequently focus on traits specific to each species, including size, weight, sugar and acid content, ripening time, fruit storability, and post-harvest procedures. Tens of thousands of fruit genomes could be mined for sequence variants that could serve as molecular markers thanks to the availability of powerful software tools and updated sequencing techniques.

Factors Affecting Dynamic Photosynthesis under Changing Light
Major research on photosynthesis has been carried out under steady light. However, in the natural environment, steady light is rare, and light intensity is always changing. Changing light affects (usually reduces) photosynthetic carbon assimilation and causes decreases in biomass and yield. Ecologists first observed the importance of changing light for plant growth in the understory; other researchers noticed that changing light in the crop canopy also seriously affects yield.
