Safe sites for buccal shelf bone screw placement in various skeletal malocclusions: A CBCT study.

Introduction: The mandibular buccal shelf area is an extra-alveolar anchorage site that has high quality and quantity of bone, provides biomechanical benefits and has low failure rates. It is essential to place the implant in the region of bone with optimal thickness. The aim of this study was to determine the suitable site of the mandibular buccal shelf for bone screw insertion at 90 degrees and 30 degrees angles of insertion and various heights, angulations, areas of the buccal shelf in prognathic and retrognathic mandibles, and vertical and horizontal growth patterns.

In vitro virulotyping, antifungal susceptibility testing and DNA fingerprinting of Microsporum canis strains of canine and feline origin.

Microsporum canis is considered the common dermatophyte agent associated with ringworm in felines and canines. In the present study, we sampled n = 548 felines and canines for the probable isolation of M. canis.

Molecular epidemiology of Trichophyton infections among canines from Northern India.

Dermatophytes are keratinophilic fungi that cause skin infections in both humans and animals. Recently, the incidence rates of fungal infections associated with Trichophyton spp. have been considered endemic in many locations.

Dermatophytosis caused by Nannizzia nana (Microsporum nanum): a comprehensive review on a novel pathogen.

Keratinophilic fungi are mostly soil-inhabiting organisms with occasional infections in humans and animals. Even though most dermatophytes are host-adapted, cross-species infections are common by zoophilic and geophilic dermatophytes. N.

Advances in drying techniques for retention of antioxidants in agro produces.

Antioxidants are compounds that are essential for the human body which prevents cell from disease causing free radicals. Antioxidants are present in a wide range of fruits, vegetables, and spices. However, a considerable amount of antioxidants is lost during the post-harvest drying operation of agro produces for their shelf-life enhancement.

Detection of chlorpyrifos based on molecular imprinting with a conducting polythiophene copolymer loaded on multi-walled carbon nanotubes.

Molecular imprinting technique (MIT) with electrochemical sensing provides an attractive tool for the fabrication of sensors. Incorporation of conducting copolymer and surface imprinting strategies in the sensing device improves the conducting properties and poor template accessibility, slow binding kinetics at the same time. Here, this technique was employed with conducting polymers with multi-walled carbon nanotubes (MWCNT) to build an electrochemical sensor for detecting Chlorpyrifos (CPF) in vegetable sample solutions.

Pathotyping and antimicrobial susceptibility testing of Escherichia coli isolates from neonatal calves.

Neonatal calf mortality is a major concern to livestock sector worldwide. Neonatal calf diarrhoea (NCD), an acute severe condition causes morbidity and mortality in calves. Amongst various pathogens involved in NCD, E.

Deletion of both methionine sulfoxide reductase A and methionine sulfoxide reductase C genes renders Salmonella Typhimurium highly susceptible to hypochlorite stress and poultry macrophages.

Salmonella Typhimurium survives and replicates inside the oxidative environment of phagocytic cells. Proteins, because of their composition and location, are the foremost targets of host inflammatory response. Among others, Met-residues are highly prone to oxidation.

Cyclophosphamide, a cancer chemotherapy drug-induced early onset of reproductive senescence and alterations in reproductive performance and their prevention in mice.

Although, cyclophosphamide (CP) treatment is known to cause degeneration of the ovarian follicular reserve, which may have a serious consequence of the onset of early reproductive senescence, thus far there is no experimental study either to demonstrate CP-induced early onset of reproductive senescence or its prevention. Intraperitoneal administration (ip) of CP [100 mg/kg body weight (bw)/mouse] resulted in a drastic reduction in reproductive life span as shown by the onset of reproductive senescence at a significantly early age (258 days) compared to controls (349 days), whereas treatment with the root extract of the herb (DH) (200 mg/Kg bw/day for 7 days), a cocktail of anti-oxidants prior to CP administration maintained normal reproductive life span in mice. Further, the CP treated mice showed a significant increase in pre-coital interval and a significant reduction in parturition index coupled with regressive changes in the uterine endometrium, whereas DH co-treatment prevented these changes.

Graphene oxide based functionalized chitosan polyelectrolyte nanocomposite for targeted and pH responsive drug delivery.

Graphene oxide (GO) was first modified to amine functionalized GO (AGO) and acts as a cationic polyelectrolyte. Chitosan (CS) was conjugated with folic acid (FA) through N, N´ -Dicyclohexylcarbodiimide coupling to form FA-CS. After this, itaconic acid and acrylic acid monomers are grafted to the hydroxyl group of CS using ethyleneglycol dimethacrylate as cross linker and potassium peroxydisulfate as an initiator to generate -COOH functional groups and forming chemically modified chitosan (CMCS).

Multiple dose treatment reduces cyclophosphamide-induced ovarian follicular loss in mice.

This study compares the effects of single dose and multiple dose treatment of cyclophosphamide (CP) on oxidative stress-mediated follicular damage in mouse ovary. In the first experiment, adult female mice were administered with a single dose of CP (100 mg/kg body weight/mouse) and autopsied 72 hr after treatment. In the second experiment, adult female mice were injected with multiple doses of CP (40 mg/kg body weight/day/mouse for 10 consecutive days) and sacrificed on Day 11.

Alternative mechanisms of inhibiting activity of poly (ADP-ribose) polymerase-1.

Poly ADP-ribose polymerase (PARP-1), a DNA nick-sensor enzyme, is an abundant nuclear protein. Upon sensing DNA breaks, PARP-1 gets activated and cleaves NAD into nicotinamide and ADP-ribose and polymerizes the latter onto nuclear acceptor proteins including histones, transcription factors, and PARP-1 itself. Poly(ADP-ribosylation) mainly contributes to DNA repairing mechanism.

Chemopreventive and therapeutic potential of chrysin in cancer: mechanistic perspectives.

Chrysin, a naturally occurring flavone, abundantly found in numerous plant extracts including propolis and in honey is one of the most widely used herbal medicine in Asian countries. Nowadays, chrysin has become the foremost candidate exhibiting health benefits, owing to its multiple bioactivities such as antioxidant, anti-inflammatory, anti-allergic, anti-diabetic, anti-estrogenic, antibacterial and antitumor activities. Anticancer activity is most promising among the multiple pharmacological effects displayed by chrysin.
