Target-binding small proteins are promising alternatives to conventional monoclonal antibodies (mAbs), offering advantages in terms of tissue penetration and manufacturing costs. Recently, a design strategy to create small proteins called fluctuation-regulated affinity proteins (FLAPs) consisting of a structurally immobilized peptide from the complementarity-determining region (CDR) loops of mAbs (CDR-derived peptide) and a protein scaffold was developed. Because mAb paratopes are usually composed of multiple CDRs, FLAPs with multiple binding peptides may have an enhanced target-binding capability. Here, a strategy to create FLAPs bearing dual CDR-derived peptides (D-FLAPs) using the anti-human epithelial growth factor receptor type 2 (HER2) mAb trastuzumab as a basis is developed. Computationally selected CDR-derived peptides are first grafted onto two adjacent loops of the fibronectin type III domain (FN3) scaffold, yielding 80 D-FLAP candidates. After computational screening based on their similarity to the parental mAb with regard to the conformation of paratope residues, two candidates are selected. After further evaluation with ELISA, one D-FLAP with HYTTPP and GDGFYA peptides from CDR-L3 and CDR-H3 of the parental mAb, respectively, is found to bind HER2 with a dissociation constant of 58 nm. This method applies to various mAb drugs and allows the rational design of small protein alternatives.The development of molecular catalysts for CO2 electroreduction within electrolyzers requests their immobilization on the electrodes. While a variety of methods have been explored for the heterogenization of homogeneous complexes, a novel approach using a hierarchical porous carbon material, derived from a metal-organic framework, is reported as a support for the well-known molecular catalyst [Re(bpy)(CO)3 Cl] (bpy=2,2'-bipyridine). This cathodic hybrid material, named Re@HPC (HPC=hierarchical porous carbon), has been tested for CO2 electroreduction using a mixture of an ionic liquid (1-ethyl-3-methylimidazolium tetrafluoroborate, EMIM) and water as the electrolyte. Interestingly, it catalyzes the conversion of CO2 into a mixture of carbon monoxide and formic acid, with a selectivity that depends on the applied potential. The present study thus reveals that Re@HPC is a remarkable catalyst, enjoying excellent activity (turnover numbers for CO2 reduction of 7835 after 2 h at -1.95 V vs. Fc/Fc+ with a current density of 6 mA cm-2 ) and good stability. These results emphasize the advantages of integrating molecular catalysts onto such porous carbon materials for developing novel, stable and efficient, catalysts for CO2 reduction.Tangential flow filtration (TFF) has many advantages for bioreactor harvesting, as the permeate could be introduced directly to the subsequent capture step. However, membrane fouling has limited its widespread use. This is particularly problematic given the high cell densities encountered today. Here, a reverse asymmetric membrane, where the more open surface faces the feed stream and the tighter barrier layer faces the permeate stream, has been investigated. The open surface contains pores up to 40 μm in diameter while the tighter barrier layer has an average pore size of 0.4 μm. Filtration of yeast suspensions has been conducted under a range of conditions. The yeast cells are trapped in the open pore structure. The membrane stabilizes an internal porous cake that acts like a depth filter. This stabilized cake layer can remove particulate matter that would foul the barrier layer if it faced the feed stream. As filtration continues, a surface cake layer forms on the membrane surface. IWP-4 datasheet A resistance in series model has been developed to describe the permeate flux during TFF. The model contains three fitted parameters which can easily be determined from constant pressure normal flow filtration experiments and total recycle constant flux TFF experiments. The model can be used to estimate the capacity of the filter for a given feed stream. Our results suggest that using a reverse asymmetric membrane could avoid severe flux decline associated with fouling of the barrier layer during bioreactor harvesting.
The purpose of this study was to examine the trajectory of psychological distress and well-being across the coronavirus pandemic by BMI category and weight discrimination.

Participants (N = 1,590) were assessed three times early February 2020 before the coronavirus crisis in the United States and again in mid-March and late April 2020. Participants reported their weight, height, and weight discrimination in February. Depressed affect, loneliness, purpose in life, life satisfaction, and perceived support were assessed in all surveys; anxiety and stress were assessed in the March/April surveys.

Prior to the pandemic, reporting weight discrimination or being in the underweight or obesity 2 to 3 categories was associated with more distress and lower well-being. Weight discrimination, not BMI, was associated with a twofold increased risk of incident depression from before to during the pandemic. Weight discrimination was associated with declines in purpose in life and life satisfaction across the pandemic. BMI categories were unrelated to changes in distress/well-being across the pandemic.

Prior to the pandemic, BMI and weight discrimination were vulnerabilities for greater distress and lower well-being. Weight discrimination, but not BMI, increased risk for incident depression and declines in well-being during the coronavirus pandemic.

Choosing which patients to recommend surgery for benign thyroid conditions can be difficult due to the subjective nature of compressive thyroid and hormonal symptoms. The aim of this prospective study was to analyse changes in quality of life (QOL) following thyroid surgery using a validated disease-specific assessment tool, the thyroid-related patient-reported outcome (ThyPRO) questionnaire.

Participants undergoing elective thyroid surgery for benign conditions were recruited. Patient demographics and clinical data were collected. ThyPRO consists of 85 questions grouped into 13 physical, mental and social symptom domains. Patients completed a ThyPRO questionnaire pre-operatively and at 6 weeks and 6 months post-operatively. ThyPRO items were scored according to protocol to produce 13 subscales. Repeated measures linear models with no random effects were performed using data for each outcome.

Results were available for a total of 72 patients. The sample was predominately female (n = 63, 88%) with average age 49.
