The Association of the Microbiome with Melanoma Tumor Response to Immune Checkpoint Inhibitor Treatment and Immune-Related Adverse Events (NCT05102773).

Improved understanding of the factors that underlie immune checkpoint inhibitor (ICI) response and toxicity are needed as only half of patients with metastatic melanoma respond, and 10-40% experience immune-related adverse events (irAEs). Modifying the gut microbiome could positively affect response to ICIs and reduce toxicities. Here, we sought to determine if the pre-treatment gut microbiome predicts ICI response or toxicity in the setting of metastatic melanoma.

[Enzyme engineering in microbial biosynthesis of terpenoids: progress and perspectives].

Terpenoids, known for their structural and functional diversity, are highly valued, especially in food, cosmetics, and cleaning products. Microbial biosynthesis has emerged as a sustainable and environmentally friendly approach for the production of terpenoids. However, the natural enzymes involved in the synthesis of terpenoids have problems such as low activity, poor specificity, and insufficient stability, which limit the biosynthesis efficiency.

Transoral Odontoidectomy - Our Experience in A Limited-Resource Setup.

Background: Although posterior procedures are used for most cases of basilar invagination, transoral decompression is an important tool in complex deformities with severe degeneration and neural compression.

Methods: Consecutive patients who underwent transoral odontoidectomy for basilar invagination and atlantoaxial dislocation at the neurosurgical unit of Lady Reading Hospital Peshawar between June 2016 and January 2022 were retrospectively included. Preoperative and postoperative neurological, clinical, and radiological parameters were recorded and compared.

Prebiotic potential of enzymatically prepared resistant starch in reshaping gut microbiota and their respond to body physiology.

The increase in consumer demand for high-quality food products has led to growth in the use of new technologies and ingredients. Resistant starch (RS) is a recently recognised source of fibre and has received much attention for its potential health benefits and functional properties. However, knowledge about the fate of RS in modulating complex intestinal communities, the microbial members involved in its degradation, enhancement of microbial metabolites, and its functional role in body physiology is still limited.

Anterior transcervical release with posterior atlantoaxial fixation for neglected malunited type II odontoid fractures.

Background: Type 2 odontoid fractures are associated with a high rate of nonunion without surgical treatment. If neglected, they may become fixed in an abnormal position, causing progressive myelopathy. Conventionally, odontoidectomy or transoral release is performed to relieve symptoms in such cases.

Case of pedicle lag screw fixation for oblique axis body and pars fractures with displacement.

Background: Multiple axis fractures with instability are rare and appropriate treatment modalities have not been established.

Case Description: A 33-year-old male presented with severe neck pain, bilateral upper-extremity numbness, and brisk reflexes in both lower extremities of 14 days' duration after a car accident. The cervical CT revealed an oblique C2 body fracture and asymmetrical neural ring fractures, while the MRI showed a normal C2-3 disk.

Microbial Pretreatment of Chicken Feather and Its Co-digestion With Rice Husk and Green Grocery Waste for Enhanced Biogas Production.

To utilize wastes and residues sustainably and excellently, there is a need to fend for efficient methods and resources for biogas production. Use of poultry waste for biogas production represents one of the most important routes toward reaching global renewable energy targets. The current study involves microbial pretreatment of chicken feather waste, followed by its co-digestion with rice husk and green grocery waste in batch and continuous reactors, respectively.

Chemically Modified Quinoidal Oligothiophenes for Enhanced Linear and Third-Order Nonlinear Optical Properties.

In the present investigation, quantum chemical calculations have been performed in a systematic way to explore the optoelectronic, charge transfer, and nonlinear optical (NLO) properties of different bis(dicyanomethylene) end-functionalized quinoidal oligothiophenes. The effect of different conformations (linking modes of thiophene rings) on conformational, optoelectronic, and NLO properties are studied from the best-performed dimer to octamer. The optical and NLO properties of all the selected systems () are calculated by means of density functional theory (DFT) methods.

Effect of salicylic acid supplementation on blood glucose, lipid profile and electrolyte homeostasis in gentamicin sulphate induced nephrotoxicity.

This study was designed to investigate effect of salicylic acid supplementation in gentamicin- induced nephrotoxicity. For this purpose, twenty four male albino rabbits were divided into 4 groups (n=6); control group, healthy untreated rabbits; gentamicin group, received only gentamicin (80mg/kg); gentamicin + salicylic acid group, received gentamicin (80mg/kg) + salicylic acid (80mg/kg) and salicylic acid group, received only salicylic acid (80mg/kg) through intra peritoneal route for 21 consecutive days. Biochemical evaluation was carried out by assessment of body weights and by estimating plasma glucose, lipid profile and electrolyte homeostasis.

Evaluating the Effect of Ionic Liquid on Biosorption Potential of Peanut Waste: Experimental and Theoretical Studies.

Peanut skin having polyphenols as major constituents is a natural, abundant, and environmentally friendly potent biosorbent for aquatic pollutants such as heavy metals. Its natural potential can be enhanced several times by treating it with ionic liquids-the green solvents. This report presents a complete study on biosorption of divalent cadmium ions using ionic liquid-treated peanut skin.

Recent developments in the synthesis of regioregular thiophene-based conjugated polymers for electronic and optoelectronic applications using nickel and palladium-based catalytic systems.

Thiophene-based conjugated polymers hold an irreplaceable position among the continuously growing plethora of conjugated polymers due to their exceptional optical and conductive properties, which has made them a centre of attention for the past few decades and many researchers have contributed tremendously by designing novel strategies to reach more efficient materials for electronic applications. This review aims to highlight the recent (2012-2019) findings in design and synthesis of novel thiophene-based conjugated polymers for optical and electronic devices using organometallic polycondensation strategies. Nickel- and palladium-based protocols are the main focus of this account.

Rare presentation of iron deficiency anaemia with cerebral venous sinus thrombosis in a middle-aged woman.

This is a case of a female patient presented with a mild headache associated with recurrent episodes of nausea and vomiting, confusion and right-sided hemiparesis, diagnosed of haemorrhagic venous infarction from the thrombosis of left transverse and sigmoid sinus and probably the left vein of Labbe. She had severe microcytic hypochromic anaemia due to iron deficiency, without any other risk factors for cerebral venous thrombosis such as trauma history, infections, coagulation disorders or autoimmune diseases. She had a good prognosis after iron supplementation and anticoagulation therapy.

Unregulated usage of labour-inducing medication in a region of Pakistan with poor drug regulatory control: characteristics and risk patterns.

Background: In developing countries such as Pakistan, poor training of mid-level cadres of health providers, combined with unregulated availability of labour-inducing medication can carry considerable risk for mother and child during labour. Here, we describe the exposure to labour-inducing medication and its possible risks in a vulnerable population in a conflict-affected region of Pakistan.

Methods: A retrospective cohort study using programme data, compared the outcomes of obstetric risk groups of women treated with unregulated oxytocin, with those of women with regulated treatment.
