Note: The type material was not examined directly, but rather examined with its images available in OSF along with the original description (Ingrisch 2001b) and compared with the materials at hand. Annotated specific diagnosis. This species has typical characters of Skejotettix gen. nov.: Brachynotal species with the upper point of insertion of antennal grooves at the lower level of compound eyes (in between the eyes in Coptotettix), reduced hindwings as well as intact nature of the median carina. Therefore, Coptotettix muglingi is very close to Skejotettix gen. nov. and does not belong to Coptotettix: I transfer this species to the genus Skejotettix gen. nov. However, Coptotettix does not have clear characters. So, a review is needed. Removing the species from Coptotettix is just one small step towards its natural organization.Published as part of Subedi, Madan, 2022, A new genus and a new groundhopper species from Nepal (Orthoptera: Tetriginae Skejotettix netrajyoti gen. et sp. nov.), pp. 35-54 in Zootaxa 5205 (1) on pages 41-43, DOI: 10.11646/zootaxa.5205.1.3, http://zenodo.org/record/728583

Demirjian's 8 teeth method for Dental age estimation in Nepalese population
No full textIt is a dataset of the study conducted with objectives of applying Demirjian’s 8 teeth method to estimate age in the Nepalese Population. We had used the Orthopantomographs of Nepalese people of age above five and less than 23 years. The radiographs were compared to the ‘Tooth Development Chart’ and each tooth studied was assigned with any one of the 10 developmental stages using Demirijian’s 8 teeth method and total maturity scores determined from them

CD16a with oligomannose-type N-glycans is the only “low-affinity” Fc γ receptor that binds the IgG crystallizable fragment with high affinity in vitro
No full textFc γ receptors (FcγRs) bind circulating IgG (IgG1) at the surface of leukocytes. Antibodies clustered at the surface of a targeted particle trigger a protective immune response through activating FcγRs. Three recent reports indicate that the composition of the asparagine-linked carbohydrate chains (N-glycans) of FcγRIIIa/CD16a impacted IgG1-binding affinity. Here we determined how N-glycan composition affected the affinity of the “low-affinity” FcγRs for six homogeneous IgG1 Fc N-glycoforms (G0, G0F, G2, G2F, A2G2, and A2G2F). Surprisingly, CD16a with oligomannose N-glycans bound to IgG1 Fc (A2G2) with a KD = 1.0 ± 0.1 nM. This affinity represents a 51-fold increase over the affinity measured for CD16a with complex-type N-glycans (51 ± 8 nM) and is comparable with the affinity of FcγRI/CD64, the sole “high-affinity” FcγR. CD16a N-glycan composition accounted for increases in binding affinity for the other IgG1 Fc glycoforms tested (10–50-fold). This remarkable sensitivity could only be eliminated by preventing glycosylation at Asn162 with an Asn-to-Gln mutation; mutations at the four other N-glycosylation sites preserved tighter binding in the Man5 glycoform. None of the other low-affinity FcγRs showed more than a 3.1-fold increase upon modifying the receptor N-glycan composition, including CD16b, which differs from CD16a by only four amino acid residues. This result indicates that CD16a is unique among the low-affinity FcγRs, and modifying only the glycan composition of both the IgG1 Fc ligand and receptor provides a 400-fold range in affinities.This research was originally published in the Journal of Biological Chemistry.

Two different variations in color as mentioned in the original description were also observed: dark grey in the individuals from the rainy season of monsoon (Figure 12C, D, E, F), and paler grey marked with light yellow on the pronotum and hind femora in the individuals from the dry season prior to monsoon (Figure 12A, B, G, H). These forms are well adapted to match the surrounding colors which provide a degree of protection against potential predators and may be considered as wet season and dry season forms.Published as part of Subedi, Madan, 2022, A new genus and a new groundhopper species from Nepal (Orthoptera: Tetriginae Skejotettix netrajyoti gen. et sp. nov.), pp. 35-54 in Zootaxa 5205 (1) on page 51, DOI: 10.11646/zootaxa.5205.1.3, http://zenodo.org/record/728583
