Our world is becoming increasingly urbanized with a growing human population concentrated around cities. The expansion of urban areas has important consequences for biodiversity, yet the abiotic drivers of biodiversity in urban ecosystems have not been well characterized for the most diverse group of animals on the planet, arthropods. Given their great diversity, comparatively small home ranges, and ability to disperse, arthropods make an excellent model for studying which factors can most accurately predict urban biodiversity.

Capturing phylogenetic signal from such a massive radiation can be daunting. Chalcidoidea is an excellent example of a hyperdiverse group that has remained recalcitrant to phylogenetic resolution.

Methods: A retrospective analysis of 226 consecutive neck dissections in 201 patients who underwent therapeutic neck dissection involving at least levels II-IV with a final pathologic diagnosis of mucosal SCC of the head and neck or PTC from 2010 to 2020. Specific cases of chyle leak were reviewed.

We clarify some of our objectives and demonstrate that many of the criticisms apply more to traditional approaches to taxonomy rather than to our minimalist approach.

Eight of the species groups are revised, of which five are newly established; keys are given to the species of each treated group, 22 species are newly described, and detailed life histories of several well-documented species are discussed. Revised are the Orasema coloradensis group (four species: O.

Objective: The aim of this study is to identify clinicopathologic features associated with positive margins after surgical treatment of cutaneous melanoma of the head and neck (CMHN).
Study Design: Retrospective cohort study.
Setting: National Cancer Database.
Purpose: Alopecia is a debilitating disorder affecting millions of individuals worldwide. Although challenging to treat, advances in hair restoration technologies have led to multiple viable options with excellent clinical results. This paper seeks to provide an overview of hair loss and the currently utilized techniques in hair transplantation in order to serve as a reference source for the facial plastic surgeon.

The following case documents a rare incident of a misdiagnosed CSCS with unusual outcomes of permanent Horner's syndrome and facial pain.
Presentation Of Case: A 36-year-old female presented with a slow-growing neck mass.
Biological processes are naturally regulated with high spatial and temporal resolution at the molecular, cellular, and systems level. To control and study processes with the same resolution, light-sensitive groups and domains have been employed to optically activate and deactivate protein function. Optical control is a noninvasive technique in which the amplitude, wavelength, spatial location, and timing of the light illumination can be easily controlled.

The single methionine (Met/M) residue of amyloid-beta (Aβ) peptide, at position 35 of the 42-mer, has important relevance for Aβ-induced oxidative stress and neurotoxicity. Recent in vivo brain studies in a transgenic (Tg) Alzheimer disease (AD) mouse model with Swedish and Indiana familial AD mutations in human amyloid precursor protein (APP) (referred to as the J20 Tg mouse) demonstrated increased levels of oxidative stress. However, the substitution of the Met631 residue of APP to leucine (Leu/L) (M631L in human APP numbering, referred to as M631L Tg and corresponding to residue 35 of Aβ1-42) resulted in no significant in vivo oxidative stress levels, thereby supporting the hypothesis that Met-35 of Aβ contributes to oxidative insult in the AD brain.

Mice were given either drinking water or water supplemented with N-acetylcysteine (NAC) (2 mg/kg body weight) for a period of five months. The time periods of treatment correspond to ages prior to Aβ deposition (i.
