Neuronal transmission relies on the regulated secretion of neurotransmitters, which are packed in synaptic vesicles (SVs). Hundreds of SVs accumulate at synaptic boutons. Despite being held together, SVs are highly mobile, so that they can be recruited to the plasma membrane for their rapid release during neuronal activity.

Even the most delicate endonasal surgery for skull base lesion causes changes in the nasal cavity, some of them permanent. Morphological changes in the nasal cavity and their consequences (changes in nasal airflow) are often studied by advanced numerical analysis called computational fluid dynamics. This review summarizes current knowledge of endoscopic transsphenoidal skull base surgery effects on nasal airflow.

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that leads to the death of upper and lower motor neurons. While most cases of ALS are sporadic, some of the familial forms of the disease are caused by mutations in the gene encoding for the RNA-binding protein FUS. Under physiological conditions, FUS readily phase separates into liquid-like droplets and .

Article Synopsis
  • Mature larvae and pupae of three species within the Lixini tribe have been described for the first time, highlighting their unique physical characteristics.
  • The study reveals distinctions between these species and other related genera through specific traits like endocarina presence and abdominal segment counts.
  • It argues against classifying the Rhinocyllini tribe based on larvae and pupae characteristics and suggests that both adult and immature forms can help differentiate subgenera within the genus studied, emphasizing the importance of immature morphology in taxonomy.

Mature larvae and pupae of (Scopoli, 1763) (Curculionidae: Lixinae: Cleonini) are morphologically described in detail for the first time and compared with known larvae and pupae of other Cleonini species. The results of measurements and characteristics most typical for larvae and pupae of Cleonini are newly extracted and critically discussed, along with some records given previously. Keys for the determination of selected Cleonini species based on their larval and pupal characteristics are attached.

Gene expression in human tissue has primarily been studied on the transcriptional level, largely neglecting translational regulation. Here, we analyze the translatomes of 80 human hearts to identify new translation events and quantify the effect of translational regulation. We show extensive translational control of cardiac gene expression, which is orchestrated in a process-specific manner.

The genera Pascoe, 1866 and Aurivillius, 1911 (Cerambycidae: Lamiinae: Morimopsini), both endemic to Borneo, are revised. Four species of are recognized: Pascoe, 1886 (Malaysia: Sabah), Sudre, 1997 (Malaysia: Sarawak), (Malaysia: Sarawak), and (Brunei). is a monotypic genus containing Aurivillius, 1911 (Malaysia: Sarawak) which is known only from the holotype.

Understory herbs and soil invertebrates play key roles in soil formation and nutrient cycling in forests. Studies suggest that diversity in the canopy and in the understory are positively associated, but these studies often confound the effects of tree species diversity with those of tree species identity and abiotic conditions. We combined extensive field sampling with structural equation modeling to evaluate the simultaneous effects of tree diversity on the species diversity of understory herbs, beetles, and earthworms.

The mature larvae and pupae of Lixus (Ortholixus) bituberculatus Smreczyński, 1968 and Lixus (Dilixellus) neglectus Fremuth, 1983 (Curculionidae: Lixinae: Lixini) are described and compared with known larvae of 21 other Lixus and 2 Hypolixus taxa. The mature larva and pupa of Lixus bituberculatus are the first immature stages described representing the subgenus Ortholixus. The larva of Lixus neglectus, in the subgenus Dilixellus, is distinguished from the known larvae of four species in this subgenus by having more pigmented sclerites on the larval body.

We reviewed the species of genus Dolichostyrax Aurivillius (Cerambycidae: Morimopsini) from Borneo, which included the redescriptions of two species - Dolichostyrax moultoni Aurivillius, 1911 and Dolichostyrax longipes Aurivillius, 1913, with the first female description for the latter. After the examination of the additional material previously identified as Dolichostyrax, we described three new genera - Borneostyrax gen. n.

Mature larva and pupa of Adosomus (s. str.) roridus (Pallas, 1781) (Curculionidae: Lixinae: Cleonini) are described and compared with ten other taxa of Cleonini with known larvae.

Proteases and their inhibitors have long been investigated in numerous tumor systems, and at the tumor growing front, their balance has been universally found to be shifted towards higher proteolytic activities. However, out of many promising serine and metalloproteinase inhibitors, none are included in cancer treatment regimens at present. The current search for active antiproteolytic compounds is in contrast to the classical approach developed by John Beard, who suggested treating advanced cancer by fresh pancreatic extracts whose antitumor activity was based on their proteolytic potential.
