The influence of tumor topography on the surgical outcome of craniopharyngiomas.

Objective: Various topographical classifications for craniopharyngioma have been proposed based on their relationship with optic chiasm and the third ventricular floor. There is a paucity of literature evaluating the surgical outcome based on tumor topography. This study aims to compare the surgical outcomes of retrochiasmatic craniopharyngiomas (RCPs) and nonretrochiasmatic craniopharyngiomas (non-RCPs).

Analysis of Prognostic Factors, Extent of Resection, and Long-Term Outcome of Craniopharyngioma in Adults and Children.

Introduction: Surgical management of craniopharyngioma is debatable and still lacks clear guidelines. Long-term complications are attributed to radical resection of the tumor. Extent of resection may not be the only factor which determines the functional outcome, because studies have reported hypothalamic and visual morbidities even with conservative resection.

Modulation of the PGE-Mediated Pathway in the Eclosion Blocking Effect of Flumethrin and Terpenoid Subfraction Isolated from in .

Prostaglandins are a group of important cell-signaling molecules involved in the regulation of ovarian maturation, oocyte development, egg laying and associated behaviors in invertebrates. However, the presence of prostaglandin E (PGE), the key enzymes for PGE biosynthesis and its interference by drugs were not investigated previously in the ovary of ticks. The present study was undertaken to assess the modulation of the PGE-mediated pathway in the eclosion blocking effect of flumethrin and terpenoid subfraction isolated from in ticks.

Disposition Kinetics of Amitraz in Lactating Does.

Amitraz, a member of the formamidine pesticide family, commonly used for ectoparasite control, is applied as a dip or low-pressure hand spray to cattle and swine, and the neck collar on dogs. Data on amitraz were generated mainly on laboratory animals, hens, dogs, and baboons. The data on the toxicity and disposition of amitraz in animals and its residues in the milk are inadequate.

Influence of Pyrexia on Pharmacokinetics of Azithromycin and Its Interaction With Tolfenamic Acid in Goats.

Azithromycin is a macrolide antimicrobial agent of the azalide group with a broad spectrum of activity against gram-negative and gram-positive bacterial organisms. Tolfenamic acid is a non-steroidal anti-inflammatory drug of the fenamate group, which is used extensively in humans and animals due to its anti-inflammatory, analgesic, and antipyretic properties. There is dearth of literature on any type of drug interaction between azithromycin and tolfenamic acid in any species, including human beings and alteration of its pharmacokinetics by fever.

Adult craniopharyngioma: The role of extent of resection in tumor recurrence and long-term functional outcome.

Objective: The optimal therapeutic approach to craniopharyngioma has not been established conclusively. The surgical outcome following radical excision and conservative resection with adjuvant radiotherapy are comparable or even better with the later in pediatric or mixed populations. This study is aimed at reviewing the role of extent of resection in local tumor control and long-term outcome in adults with craniopharyngioma.

Ticks and accompanying pathogens of domestic and wild animals of Kerala, South India.

The objective of the present study was to detect the chosen nucleotide DNA or RNA sequences of the pathogens in ticks of domestic and wild animals of Kerala, South India based on molecular techniques. Among 602 ticks collected, 413 were from bovines (cattle and buffalo), 26 from goats, 101 from dogs and 62 from wild animals. Amblyomma integrum, Am.

Long-term outcome and prognostic factors of intramedullary spinal hemangioblastomas.

Spinal hemangioblastomas constitute 1.6-5.8% of all spinal cord tumors.

In vitro efficacy of amitraz, coumaphos, deltamethrin and lindane against engorged female Rhipicephalus (Boophilus) annulatus and Haemaphysalis bispinosa ticks.

The present study compares the in vitro efficacy of four chemical acaricides, viz. amitraz, coumaphos, deltamethrin and lindane, against Rhipicephalus (Boophilus) annulatus and Haemaphysalis bispinosa ticks based on adult immersion tests. Amitraz, at 350 ppm, elicited 29.

Comparison of in vitro acaricidal effects of commercial preparations of cypermethrin and fenvalerate against Rhipicephalus (Boophilus) annulatus.

Commercially available preparations of cypermethrin (Clinar and Ectomin) and fenvalerate (Flytik and Ticomax, 20% E.C) were compared for their acaricidal activity against Rhipicephalus (Boophilus) annulatus using adult immersion test. Adult tick mortality was higher with Ectomin compared to Clinar.

Determination of LC50 and LC95 values of fipronil against Haemaphysalis bispinosa based on adult immersion test.

The pattern of mortality of Haemaphysalis bispinosa ticks against fipronil was studied based on adult immersion test. Mortality occurred during 10-19 days post-treatment. The LC50 and LC95 values were calculated as 0.

Toxicity of DMSO, Triton X 100 and Tween 20 against Rhipicephalus (Boophilus) annulatus.

The problems associated with synthetic chemical pesticides include resistance, residues, pest resurgence and the adverse effects on non-target organisms. Hence, many ecofriendly newer alternatives are being evaluated among which one of the most important is the use of herbal agents. Many of the plant extracts or its fractions are dissolved in polar or non polar solvents or detergents before tested for acaricidal activity.

Acaricidal activity of Cassia alata against Rhipicephalus (Boophilus) annulatus.

Using adult immersion test, the acaricidal activity of ethanolic extracts of leaves of Cassia alata L. was studied against Rhipicephalus (Boophilus) annulatus. The efficacy was assessed by measuring per cent adult mortality, inhibition of fecundity and hatching rate.
