In this study, we introduce a new extension of the Fréchet distribution known as the new extended Fréchet (NE_Fr) model. The NE_Fr is created by combining the new extended family of distributions and the Fréchet distribution. The NE_Fr has more flexibility than the classical Fréchet distribution and some generalizations of the Fréchet distribution.

Background: Colorectal neoplasia is a multistep process that can lead to the development of colorectal cancer. Colonoscopy is the gold standard for diagnosis and screening of colorectal cancer, but its uptake is often hindered by unpleasant experiences and logistic obstacles. Therefore, non-invasive biomarker tests such as the M2-pyruvate kinase (M2PK) test have been explored as a potential screening tool.

Some important properties of the model are developed, such as quantile function, stochastic ordering, model series representation, moments, stress-strength reliability parameter, Renyi entropy, order statistics, and moment of residual life. A particular member called new extended Topp-Leone exponential (NETLE) is discussed.

It presents with a variety of symptoms including but not limited to nasal obstruction, runny nose, postnasal drip, and nasal bleeding. The main stay of treatment is surgery, but other adjuvant treatments including radiotherapy and photodynamic therapy have been used with varying degrees of successes.

The survival of breast cancer is increasing in developed countries with improved treatment modalities, while still very poor in developing countries. In Nigeria, few breast cancer survival data are available.

The financial burden of cancer affects not only cancer patients and their families, but also the society as a whole. In Nigeria there is a dearth of information about the financial burden of cancer on patients.

The new model possesses an increasing, decreasing, unimodal and bathtub failure rates depending on the parameters. The relationship of PoiGHL with the exponentiated Weibull Poisson (EWP), Poisson exponentiated Erlang-truncated exponential (PEETE), and Poisson generalized Gompertz (PGG) model is discussed.

Documented data on the Human Immune-deficiency Virus (HIV) seroprevalence among patients with cervical cancer in our environment are scarce.
Objective: The aim of this study is to determine the prevalence of HIV infection in women with cancer of the cervix.
Resveratrol (RESV) and Environmental Enrichment (EE) have been separately reported to protect organisms against various diseases. This study investigated the potential benefit of the combination of RESV and EE on biomarkers of oxidative stress in young healthy mice. Fifty mice of both sexes were randomly divided into five groups of 10 animals each: group I served as control, group II were maintained on alternate day feeding, group III received RESV 50 mg/kg, suspended in caboxymethylcellulose orally per kg/day.

Materials And Methods: Phenotypic methods used includes microscopic technique, colony morphology study, catalase-coagulase tests, and the use of mannitol salt agar test, oxacillin resistance screening agar base, and antibiotic susceptibility testing methods. Genotypic approach was used for deoxyribonucleic acid extraction, and the presence of nuc and mecA gene was detected using polymerase chain reaction (PCR) techniques.
Research on the effects of Mobile phone radio frequency emissions on biological systems has been focused on noise and vibrations as auditory stressors. This study investigated the potential effects of exposure to mobile phone electromagnetic field radiation, ringtone and vibration on anxiety-like behaviour and oxidative stress biomarkers in albino wistar rats. Twenty five male wistar rats were randomly divided into five groups of 5 animals each: group I: exposed to mobile phone in switched off mode (control), group II: exposed to mobile phone in silent mode, group III: exposed to mobile phone in vibration mode, group IV: exposed to mobile phone in ringtone mode, group V: exposed to mobile phone in vibration and ringtone mode.

Purpose: To assess the prevalence of allergic conjunctivitis in Gambia and to determine its epidemiologic features, seasonal variations and associated ocular and systemic conditions.
Methods: Records of patients clinically diagnosed with allergic conjunctivitis between April 2007 and March 2008 were reviewed. Variables including age, sex, date of presentation, and systemic and ocular findings were recorded.
