The Clinical Efficacy of Fat Injection on the Repair of Hand Flexor Tendon: A Randomized Clinical Trial.

Background: In recent years, special attention has been paid to minimally invasive and conservative methods in addition to conventional surgical methods to repair tendon damage. In this regard, the effect of fat injection and graft has been of great interest due to its potential in accelerating tissue repair. We aimed to assess the clinical efficacy of fat injection along with conventional approach in patients with flexor tendon injury.

A spatial-temporal graph deep learning model for urban flood nowcasting leveraging heterogeneous community features.

Flood nowcasting refers to near-future prediction of flood status as an extreme weather event unfolds to enhance situational awareness. The objective of this study was to adopt and test a novel structured deep-learning model for urban flood nowcasting by integrating physics-based and human-sensed features. We present a new computational modeling framework including an attention-based spatial-temporal graph convolution network (ASTGCN) model and different streams of data that are collected in real-time, preprocessed, and fed into the model to consider spatial and temporal information and dependencies that improve flood nowcasting.

Short-term inflow forecasting in a dam-regulated river in Southwest Norway using causal variational mode decomposition.

Climate change affects patterns and uncertainties associated with river water regimes, which significantly impact hydropower generation and reservoir storage operation. Hence, reliable and accurate short-term inflow forecasting is vital to face climate effects better and improve hydropower scheduling performance. This paper proposes a Causal Variational Mode Decomposition (CVD) preprocessing framework for the inflow forecasting problem.

Enriched microbial communities for ammonium and nitrite removal from recirculating aquaculture systems.

The aim of this study was the enrichment of high-performance microbial communities in biofilters for removal of ammonium and nitrite from aquaculture water. Ammonium oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB) were enriched from different environmental water samples. The microbial communities with higher ammonium and nitrite removal activity were selected and adapted to different temperatures [9 °C, 15 °C, room temperature (25 °C), and 30 °C].

Evaluating Pancreatic index in Patients with and without Metabolic Syndrome.

BACKGROUND Metabolic syndrome can be considered as a combination of metabolic disorders that may led to an increased risk of some diseases such type II diabetes, cardiovascular diseases, myocardial infarction, and is the cause of mortality from coronary artery disease. Its prevalence is particularly high in women. There is evidence that pancreatic fat, as a key factor in non-alcoholic fatty liver and metabolic syndrome, numerates as an early indicator of abnormal fat deposition.

The incidence of psychosocial disturbances during the coronavirus disease-19 pandemic in an Iranian sample.

The spreading of the Corona Virus Disease 2019 (COVID-19) pandemic could be associated with psychosocial implications. This study, therefore, aimed to investigate the psychosocial disturbances before and during the COVID-19 pandemic. The cross-sectional study included 20,885 participants (12,343 females and 8,542 males) with psychosocial trauma who were selected by the census sampling method from Fars province, Iran.

Brain magnetic resonance imaging without contrast significantly increased serum levels of IL-6, but not IL-10, IL-17A and TGF-β.

: Magnetic Resonance Imaging (MRI) is a non-invasive imaging modality. However, the effects of MRI on the immune system in the in vivo conditions are yet to be clarified. In this study we explored the effects of routine brain MRI on the protein and mRNA peripheral blood levels of interleukin-6 (IL-6), IL-10, IL-17A and transforming growth factor-beta (TGF-β).

Effect of essential oil and potassium sorbate on inoculated , microbial and chemical quality of raw trout fillet during refrigerator storage.

Human listeriosis is predominantly associated with contaminated food consumption, including seafood, shrimp, and RTE foods. is a foodborne pathogen that is mainly found in freshwater, seawater, and fish mucus. Seafood contamination can occur during food processing.

Evaluation of different direct and indirect SELEX monitoring methods and implementation of melt-curve analysis for rapid discrimination of variant aptamer sequences.

Systematic Evolution of Ligands by Exponential enrichment (SELEX) is an iterative method for in vitro selection of aptamers from a random synthetic oligonucleotide library. Successful retrieving of aptamers by SELEX relies on optimization of various steps including target immobilization, aptamer partitioning, amplification, and ssDNA generation, which all require spending considerable effort and cost. Furthermore, due to the random nature of the initial library, SELEX may redirect toward the selection of low-affinity aptamers that are over-represented in the ssDNA population due to PCR bias.

Effects of nanosilver on hematologic, histologic and molecular parameters of rainbow trout (Oncorhynchus mykiss).

Efficient antibacterial and antifungal properties of silver nanoparticles (AgNPs) sparked its commercial application in several industrial and household products. Drastic increase of AgNPs production raised concerns over aquatic organisms' exposure. The toxic dose, mechanism of toxicity, physiological damages, gene expression alteration, hematological and blood parameter distortion by AgNP needs to be investigated to explore inevitable risk in aquatic animals.

Triiodothyronine reduces toxic effects of diazinon in Persian sturgeon (Acipenser persicus) embryos.

Thyroid hormones (THs) play an important role in early stages development of fish species. Manual elevation of THs in the embryos improves viability and hatching success. However, the impacts of endocrine disrupting chemicals on THs-treated embryos are unclear.

Droplet vitrification versus straw cryopreservation for spermatozoa banking in Persian sturgeon (Acipenser persicus) from metabolite point of view.

Persian sturgeon (Acipenser persicus), a commercially valuable and critically endangered fish species has been suffering considerable declines in populations in the nature due to over-fishing, habitat destruction and marine pollution during past decades. Since there were no achievements in artificial reproduction programs, genetic resource banking such as gametes and embryo cryopreservation can be a good strategy however, reported resulting gamete qualities were considerably low. In the present study, the metabolome content of Persian sturgeon spermatozoa was investigated during common straw cryopreservation and novel droplet vitrification by the use of H NMR (Nuclear Magnetic Resonance) spectroscopy.

H NMR metabolic profiling of the cryopreserved spermatozoa of the wild endangered Persian sturgeon (Acipenser persicus) with the use of beta-cyclodextrin as an external cryoprotectant.

Persian sturgeon (Acipenser persicus) is an endangered species and genetic resource banking such as gametes and embryo preservation could be one of the most pursued conservation approaches. In this study, deleterious effects of the traditional cryopreservation technique and the effect of different doses of 2-hydroxypropyl-beta-cyclodextrin (HβCD) on thawed spermatozoa quality (motility duration and percentage) of Persian sturgeon (Acipenser persicus) were investigated from metabolic aspects of view. For cryopreserving, semen was diluted with Tris-HCl (100 mM) extenders containing 0, 5, 10, and 15 mM of HβCD in a ratio of 1:1 (semen/extenders).
