Recent advances and challenges in single cell protein (SCP) technologies for food and feed production.

The global population is increasing, with a predicted demand for 1250 million tonnes of animal-derived protein by 2050, which will be difficult to meet. Single-cell protein (SCP) offers a sustainable solution. This review covers SCP production mechanisms, microbial and substrate choices, and advancements in metabolic engineering and CRISPR-Cas.

First report of causing root rot on in China.

Soil-borne plant-pathogenic spp. can cause root rot and damping off on important plant species, resulting in serious economic loss. A survey in October 2021 identified soil-borne diseases occurring on in Yunnan Province, China.

First report of causing leaf spot disease on in China.

The macadamia industry is developing rapidly in China. A brown leaf spot disease was noted in six plantations in Lincang, Yunnan, in October 2021. Over 60% of trees sampled had brown leaf spot symptoms, among approx.

[Application of ultrasound-guided endoscopic retrograde appendicitis therapy in children with appendix-related chronic abdominal pain].

Objectives: To study the clinical efficacy of ultrasound-guided endoscopic retrograde appendicitis therapy in children with appendix-related chronic abdominal pain.

Methods: A retrospective analysis was performed on the medical data of 30 children with the chief complaint of chronic abdominal pain who were admitted from August 2019 to May 2021. All the children were found to have inflammation of the appendix or intracavitary stool and fecalith by ultrasound and underwent ultrasound-guided endoscopic retrograde appendicitis therapy.

[Expression and Activity Regulation of Indoleamine 2,3-Dioxygenase in Acute Myeloid Leukemia Cells].

Objective: To investigate the expression and activity regulation of indoleamine 2,3-dioxygenase(IDO) in acute myeloid leukemia cells.

Methods: Expression of IDO and TLR9 in HL-60 and K562 cells cocultured with or without IFN-γ,Tα1,IFN-γ+Tα1 and chloroquine were determined by reverse transcription-polymerase chain reaction(RT-PCR). Then, the IDO activity in HL-60 and K562 cells cocultured with or without IFN-γ,Tα1,IFN-γ+ Tα1 was assayed by coomassie brilliant blue staining and modified colorimetric method.

Effect of Timing and Duration of Soil Saturation on Soilborne Pythium Diseases of Common Bean (Phaseolus vulgaris).

Understanding combined abiotic (waterlogging) and biotic (Pythium spp.) stress resistance remains an important challenge to improving common bean (Phaseolus vulgaris) productivity in disease-prone regions with irregular but intensive rainfall patterns. This study documented the effects of timing (1, 3, 5, 7, and 9 days after sowing) and duration (3, 6, 12, and 24 h) of soil saturation (waterlogging) on damping-off, as well as hypocotyl and root diseases of common bean caused by Pythium irregulare.

Activity and expression of nitric oxide synthase in pork skeletal muscles.

The objective of this study was to investigate the biochemical changes of nitric oxide synthase (NOS) in pork skeletal muscles during postmortem storage. Longissimus thoracis (LT), psoas major (PM) and semimembranosus (SM) muscles of pork were removed immediately after slaughter and stored under vacuum condition at 4°C for 0, 1 and 3d. Results showed that all three muscles exhibited NOS activity until 1d while SM muscle retained NOS activity after 3d of storage.

Species of Pythium Associated with Seedling Root and Hypocotyl Disease on Common Bean (Phaseolus vulgaris) in Western Australia.

The occurrence and distribution of Pythium spp. were determined by collecting isolates of Pythium from common bean (Phaseolus vulgaris) plants showing root or hypocotyl disease symptoms from different areas of Western Australia in 2012. Eight different Pythium species (Pythium conidiophorum, P.

Effect of nitric oxide on μ-calpain activation, protein proteolysis, and protein oxidation of pork during post-mortem aging.

The aim of the current research was to examine the influence of nitric oxide (NO) on calpain activation, protein proteolysis, and oxidation in post-mortem pork. Five longissimus muscles were removed from carcass after slaughter, and samples were incubated with water, nitric oxide synthase (NOS) inhibitor, or NO donor for 24 h at 4 °C. The samples were taken out and then stored under 4 °C for 1, 4, and 7 d.

Temporal and Spatial Changes in the Pea Black Spot Disease Complex in Western Australia.

Black spot (also referred to as Ascochyta blight, Ascochyta foot rot and black stem, and Ascochyta leaf and pod spot) is a devastating disease of pea (Pisum sativum) caused by one or more pathogenic fungi, including Didymella pinodes, Ascochyta pisi, and Phoma pinodella. Surveys were conducted across pea-growing regions of Western Australia in 1984, 1987, 1989, 1996, 2010, and 2012. In total, 1,872 fungal isolates were collected in association with pea black spot disease symptoms.
