pulmonarius, and P. ostreatus, respectively, while the moisture and ash contents of treated wastes decreased as the incubation periods progressed. However, there was no significant difference (P ≤ 0.05) in the protein, fiber, and fat content of the control compared to those of treated wastes. This study affirms that biotreatment of these agrowaste products using the selected mushrooms can enhanced their value for further use.Bioactivity is defined as the intrinsic property of compounds that enables their participation in specific biological reactions. This study aimed to evaluate the antimicrobial capacity and to separate and characterize bioactives from aqueous and hydroalcoholic extracts obtained from the mycelium of medicinal mushrooms Pleurotus albidus and Phellinus linteus. Antimicrobial activity, through the disc diffusion method, was found against strains of Bacillus cereus, B. subtilis, Pseudomonas aeruginosa, and Staphylococcus aureus. P. albidus extracts showed better activity against Bacillus strains, whereas Ph. linteus extracts had greater effectiveness against S. aureus and P. aeruginosa. Aqueous extraction was best for obtaining bioactive compounds of P. albidus, whereas 30% hydralcoholic extraction performed best for obtaining Ph. linteus. Mass spectrometry analyses allowed the identification of the main chemical compounds extracted from the fungal biomasses, including glutathione oxidase, leucovorin, and riboflavin. Taking these findings into consideration, P. albidus and Ph. linteus might be used as sources of bioactive molecules for the development of novel drugs or nutraceuticals, contributing to the improvement of public health.Cyathostomins are common intestinal nematodes that parasitize horses and can affect animal health and welfare. Alternative treatments are essential for sustainable parasite control, reducing the indiscriminate use of anthelmintics and their impacts on the environment, animals, and humans. Pleurotus spp. are edible medicinal mushrooms that possess several therapeutic properties, including antiparasitic and nematocidal activities. This study aimed to evaluate the antioxidant and nematocidal activity of aqueous extracts of three oyster species (P. florida, P. ostreatus, and P. djamor) on cyathostomine eggs in vitro. P. florida showed the highest activity against test organisms, inhibiting the hatching of eggs in up to 92.19% at the highest concentration (10%) of aqueous extract, with a mean lethal concentration (LC50) of 2.13%. In the aqueous extracts of P. ostreatus and P. djamor, nematocidal activity was reduced, inhibiting egg hatching by 55.46% (LC50, 7.44%) and 23.67%, respectively, at a concentration of 10%. P. florida showed higher antioxidant activity than that of the other species tested. Thus, P. florida may be considered a potential alternative for biological control in in vivo experiments with cyathostomins.The medicinal mushroom Leucocalocybe mongolica has received much attention from biologists since the end of the last century due to its rich bioactive compounds and high efficiency against a wide range of chronic diseases. Many years ago, L. mongolica was used in traditional Chinese medicine. About 100 chemical components have been isolated and/or identified in L. mongolica, especially fruiting bodies. This mushroom is rich in polysaccharides, sterols, lectins, laccase, amino acids, and volatile compounds. The bioactive compounds from L. mongolica possess significant pharmacological activities such as antitumor, antiproliferative, antidiabetic, and hypotensive effects. However, some bioactive characteristics of this mushroom still need further investigation to elucidate the multiple biological and pharmacological uses. Furthermore, L. mongolica requires scientific proof regarding its use to enhance milk production and mammary gland differentiation. In this review, we summarize the pharmacological and therapeutic properties of L. mongolica and provide suggestions for future research on this medicinal mushroom.For more than 6 millennia, Ganoderma species have been used in traditional Asian medicine due to their health benefits. Ganoderma synthesizes several compounds with biological activity, including lanostane-type triterpenoids like ganoderic acids (GAs), lucidones, and colosolactones. These triterpenoids have been investigated for their antiviral, hypoglycemic, and anticancer effects. GAs are highly oxygenated triterpenoids with different functional groups attached to lanostane skeleton. Their great chemical diversity makes GAs prospects for the development of new drugs to treat multiple illnesses such as cancer. The effect of GAs against cancer cells has been associated with their capability to inhibit specific targets such as STAT3, to induce apoptosis and cell cycle blockage, and to increase natural killer cell activity. Due to the biological activity of these molecules, novel strategies are being developed for Ganoderma production mainly by liquid cultivation, gene overexpression (HMGR, SQS, LS) by elicitors, and modified growing conditions (carbon and nitrogen sources, pH, temperature), which induce reactive oxygen species production, key compounds for secondary metabolism. In addition, some transcription factors are mainly expressed under stress conditions, such as cytochrome P450 genes, which participate in the regulation of triterpenoid synthesis. The fermentation process has been scaled up to a 300-L bioreactor, which shows good GA production. This article reviews current knowledge on bioactive triterpenoids of Ganoderma and their production, biosynthesis, and pharmacological properties, emphasizing gene expression in liquid culture. It also discusses the lack of information regarding other species with high potential.

To investigate the association between chemotherapy (CMT) cycles and oncological outcomes in elders with locally advanced cervical cancer (LACC) who treated with concurrent chemoradiotherapy (CCRT).

We retrospective studied 498 elders with LACC who treated with radiotherapy (RT) or CCRT between 2002 and 2018. Patients were divided into three groups RT, CCRT with 1-4 and CCRT with 5-6 cycles of CMT. We compared progression-free survival (PFS) and overall survival (OS) among the three groups and explored survival prognostic factors via multivariate analysis and time-varying analysis effect.

There were 453 eligible patients; 222, 119 and 112 patients who received RT, CCRT with 1-4 and CCRT with 5-6 cycles of CMT, respectively. Patients in the RT group had older age, poorer performance status, more treatment with conventional RT technique and earlier treatment year comparing with both CCRT groups. Patients who received 5-6 cycles of CMT were less to have underweight, comorbidities and anaemia compared with the RT group. There were patients with lower FIGO stage in 5-6 cycles than in 1-4 cycles of CMT and RT groups. The 5-year PFS and OS between RT, CCRT with 1-4 and CCRT with 5-6 cycles of the CMT group were significantly different. Performance status, comorbidity, histology, FIGO stage and total received 5-6 CMT cycles were significant prognostic factors of PFS and OS. However, the benefits of receiving 5-6 CMT cycles were evidenced only within the first 2.5 years.

Elders with LACC who received 5-6 cycles of CMT concurrently with RT can improve PFS and OS, but the benefit persisted only within the first 2.5 years.

Elders with LACC who received 5-6 cycles of CMT concurrently with RT can improve PFS and OS, but the benefit persisted only within the first 2.5 years.Two-stage implant systems result in gaps and cavities between implant and abutment that can act as a trap for bacteria and thus possibly cause inflammatory reactions in the peri-implant soft tissues. These gaps between the components are inevitable, and their clinical significance has so far been mostly neglected by both manufacturers and clinicians. This study is thus intended to evaluate microbial leakage at implant abutment interface in different implant systems. Four different systems, the Nobel tri-channel, the Nobel conical, the Equinox, and the Straumann, were used for this study. One microliter of a fresh broth suspension of Streptococcus mutans was added to the implant fixture (implant body). The implant was immersed in fresh heart brain infusion and was incubated at 37° for 48 hours. After incubation, 10 μL of the broth was made as lawn culture on sterile agar and the colonies were counted and recorded as colony-forming units per milliliter. Statistical tests were carried out on SPSS software and tests included analysis of variance (ANOVA) and P value was derived using Tukey's honestly significant difference post hoc test. After incubation, results were analyzed by evaluating the microbial leakage from each sample and it was observed that Nobel tri-channel had the least amount of microbial leakage and Equinox had maximum microbial leakage. The difference among all implant systems was statistically significant P less then 0.05. The study concluded that least micro-leakage was found in the Nobel tri-channel whereas maximum microbial leakage was present in Equinox and Straumann.The artery of Adamkiewicz (AKA) provides blood supply to the thoracolumbar spinal cord. Any disruption of the AKA can lead to the anterior spinal artery (ASA) syndrome, with devastating systematic and neurologic complications for the patient. This is a narrative review of the anatomy of AKA, the characteristics of ASA syndrome and the role of radiologic techniques in diagnosis and treatment. A detailed search of the PubMed database was conducted from January 2000 until April 2020, to locate articles relevant to our study. The references of the included studies were also retrieved in order not to miss any information. selleckchem The ASA syndrome can present as a possible post-operative complication after minimally invasive or open surgeries of multiple specialties that involve the field of spine. Risk factors associated with ASA syndrome include; kyphosis of the patient, corresponding spinal surgical approach, intraoperative hypotension, multiple ligations of the AKA, a left side approach and a 360-combined or revision surgery. The incidence varies among different operations. Many different imaging modalities have been used in preoperative plan, including but not limited to computed tomography angiography, magnetic resonance angiography, and subtraction angiography. The use of computed tomography angiography or magnetic resonance angiography preoperatively can play a major role in the prevention of the ASA syndrome. However, more research needs to be done before making any final assumptions.Detection of location of greater palatine foramen (GPF) and its anatomical variations are vital prior to posterior maxillary surgeries. The aim of this study is to determine the anatomical position and size of the greater palatine canal and GPF using cone beam computed tomography (CBCT) scan. To determine the anatomical foramen position, the posterior maxilla area was divided into five regions on the axial view (A to E from the mesial surface of the second molar to distal surface of third molar). The length of the canal was investigated on both coronal and sagittal views. Independent t-test was used to analyze the data. Among 80 females and 68 males, the anatomical position of the GPF was mainly located in region E on the left (55%) and the right (50%), and then, respectively, in region D and region C. The mean diameter of GPF was 4/48 mm on the left and 4/63 mm on the right side (P = 0/01). The average length of the canal on the coronal view was 29.46 mm on the left side and 29.75 mm on the right (P = 0.005).
