The CV profile allowed us to predict structure elements like the experimentally determined structure elements. The strong correlation between the CV and precipitate ratio profiles indicates the importance of the intramolecular residue-residue contact in maintaining the tertiary structure. Additionally, the CVs between the structure elements are considerably more than those between a structure element and a linker or two linkers, indicating that the structure elements play a funda-mental role in increasing the intramolecular adhesion. Thus, we propose that the structure elements can be considered a type of "building blocks" that maintain and dictate the tertiary structures of proteins.Structural studies of color visual pigments lag far behind those of rhodopsin for scotopic vision. Using difference FTIR spectroscopy at 77 K, we report the first structural data of three primate color visual pig-ments, monkey red (MR), green (MG), and blue (MB), where the batho-intermediate (Batho) exhibits photo-equilibrium with the unphotolyzed state. This photo-chromic property is highly advantageous for limited samples since the signal-to-noise ratio is improved, but may not be applicable to late intermediates, because of large structural changes to proteins. Here we report the photochromic property of MB at 163 K, where the BL intermediate, formed by the relaxation of Batho, is in photoequilibrium with the initial MB state. A comparison of the difference FTIR spectra at 77 and 163 K provided information on what happens in the process of transition from Batho to BL in MB. The coupled C11=C12 HOOP vibration in the planer structure in MB is decoupled by distortion in Batho after retinal photoisomerization, but returns to the coupled C11=C12 HOOP vibration in the all-trans chromophore in BL. The Batho formation accompanies helical structural perturbation, which is relaxed in BL. Protein-bound water molecules that form an extended water cluster near the retinal chromophore change hydrogen bonds differently for Batho and BL, being stronger in the latter than in the initial state. In addition to structural dynamics, the present FTIR spectra show no signals of protonated carboxylic acids at 77 and 163 K, suggesting that E181 is deprotonated in MB, Batho and BL.PCR diagnosis has been considered as the gold standard for coronavirus disease 2019 (COVID-19) and other many diseases. However, there are many problems in using PCR, such as non-specific (i.e., false-positive) and false-negative amplifications, the limits of a target sample volume, deactivation of the enzymes used, complicated techniques, difficulty in designing probe sequences, and the expense. We, thus, need an alternative to PCR, for example an ultrasensitive antigen test. In the present review, we summarize the following three topics. 4-Aminobutyric manufacturer (1) The problems of PCR are outlined. (2) The antigen tests are surveyed in the literature that was published in 2020, and their pros and cons are discussed for commercially available antigen tests. (3) Our own antigen test on the basis of an ultrasensitive enzyme-linked immunosorbent assay (ELISA) is introduced. Finally, we discuss the possibility that our antigen test by an ultrasensitive ELISA technique will become the gold standard for diagnosis of COVID-19 and other diseases.The distinguished feature of neutron as a scattering probe is an isotope effect, especially the large difference in neutron scattering length between hydrogen and deuterium. The difference renders the different visibility between hydrogenated and deuterated proteins. Therefore, the combination of deuterated protein and neutron scattering enables the selective visualization of a target domain in the complex or a target protein in the multi-component system. Despite of this fascinating character, there exist several problems for the general use of this method difficulty and high cost for protein deuteration, and control and determination of deuteration ratio of the sample. To resolve them, the protocol of protein deuteration techniques is presented in this report. It is strongly expected that this protocol will offer more opportunity for conducting the neutron scattering studies with deuterated proteins.

Latissimus dorsi (LD) flap is a workhorse flap in breast reconstruction. Despite many advantages, the primary criticism of this flap is the requirement of a second surgery to exchange expansion devices for permanent implants. This study reports a single-stage reconstruction and outcomes wherein Spectrum devices (Mentor, Irving, TX), which serve as expanders and permanent implants, are used, and expansion ports are removed under local anesthetic.

A retrospective chart review of all patients undergoing LD flap reconstruction with Spectrum device by a single surgeon at a single center during a 10-year period was performed. All patients, unilateral/bilateral, immediate/delayed were included. Details of implants, surgical procedure(s), and follow-up visits were assessed for patient outcomes.

In total, 41 patients and 56 breasts were included. Of the total patients, 58.5% retained the Spectrum device and had the expansion port removed under local anesthetic. An estimated 6 major complications occurred (14.6%), requiring return to the operating room 3 patients required a capsulectomy, 1 a capsulotomy/implant repositioning, one had loss of implant (infection), and 1 had venous congestion of the flap. Eleven minor complications occurred (26.8%) 5 seromas (3 at the breast site, 2 at the donor site), 3 delayed wound healings (2 at donor site, 1 at breast site), 1 mastectomy flap necrosis, 2 infections (1 at each breast site, 1 at donor site).

This study provides details of a single-stage LD flap with Spectrum device breast reconstruction that can be considered when performing an LD reconstruction. This technique is efficient and safe with comparable complication profile.
