Advances in fermentation technologies have resulted in the production of increased yields of proteins of economic, biopharmaceutical, and medicinal importance. Consequently, there is an absolute requirement for the development of rapid, cost-effective methodologies which facilitate the purification of such products in the absence of contaminants, such as superfluous proteins and endotoxins. Here, we provide a comprehensive overview of a selection of key purification methodologies currently being applied in both academic and industrial settings and discuss how innovative and effective protocols such as aqueous two-phase partitioning, membrane chromatography, and high-performance tangential flow filtration may be applied independently of or in conjunction with more traditional protocols for downstream processing applications.

Background: (Fabricius) (Hemiptera: Alydidae) is a major soybean pest throughout East Asia that relies on its advanced olfactory system for the perception of plant-derived volatile compounds and aggregation pheromones for conspecific and host plant localization. Odorant binding proteins (OBPs) facilitate the transport of odorant compounds across the sensillum lymph within the insect olfactory system, enabling their interaction with odorant receptors (ORs).
Methods: Real-time quantitative PCR (qRT-PCR) analyses, fluorescence-based competitive binding assays, and molecular docking analyses were applied to assess the expression and ligand-binding properties of OBP38 from .

Background: The epidemiology of vulvovaginal candidiasis (VVC) in Greece remains poorly reported and outdated.
Objectives: We therefore conducted a 2-year retrospective survey to assess the epidemiological aspects of the infection among symptomatic Greek patients.
Patients/methods: High vaginal swab samples were collected from adult women with clinically suspected VVC attending a private diagnostic laboratory in Athens.

Objective: Wet distiller's grains (WDG) are rich in crude protein, yet challenging to preserve. Nevertheless, incorporating WDG into total mixed ration (TMR) silage holds promise for enhancing fermentation quality. This study investigated the effects of varying WDG proportions on nitrogen composition, fermentation quality, and microorganisms in TMR silage.

Background: At present, 3D printing technology is becoming increasingly popular in analytical chemistry because it enables the rapid and cost-effective manufacture of sample preparation devices, particularly in flow-based operation, opening up new opportunities for the development of automated analytical methods. In parallel, the use of miniaturized methods and sustainable solvents in sample preparation is highly recommended. Accordingly, in this work, a 3D-printed millifluidic device was designed and used for the on-line natural deep eutectic solvent (NADES)-based liquid phase microextraction (LPME) coupled to a spectrofluorometer for, as a proof of concept, the determination of thiabendazole (TBZ) in fruit juice samples.

Background: Traditional lateral flow biosensors (LFBs), which utilize colorimetric signals as output, possess the virtues of simplicity and rapidity. However, it also suffers from insufficient sensitivity and limited reliability. It is well known that the results of LFBs can be false positive, and it is difficult to perform accurate quantification under low-abundance targets.
