Breast Cancer Period Prevalence in a Hazard-Exposed Cohort at Hermosillo, Sonora, Mexico: A Report from 2013-2019: OAJBS Publishers

Breast Cancer Period Prevalence in a Hazard-Exposed Cohort at Hermosillo, Sonora, Mexico: A Report from 2013-2019 by DE Villa-Guillen* in Open Access Journal of Biomedical Science (OAJBS)

Breast cancer is the leading cause of female cancer-related deaths in Mexico. Residential exposure to industrial-derived hazards may increase cancer risk. Hermosillo is one municipality with high breast cancer prevalence in Sonora, Mexico. However, the relationship between breast cancer and hazards needs further investigation. This retrospective observational study evaluated the associations between breast cancer period prevalence (years 2013-2019) and residential exposure to potentially hazardous sites (PHS) in Hermosillo. Clinical data (n=912) of breast cancer cases were collected from 6-year-old files. Cluster analysis identified regions of period prevalence. Proximity analysis classified neighbourhoods by PHS-exposure, then calculated odds ratio (OR) for breast cancer risk. Age distribution analysis evaluated the risk for PHS-exposed vs non-PHS-exposed groups. Six neighbourhoods classified as high-high breast cancer clusters. Highly industrialized neighbourhoods (≥ 7 industries vs ≤ 6 industries) presented higher risk (crude OR = 1.69), as well as those in proximity to a gas power plant (≤ 4 km vs ≥ 4 km, crude OR = 1.55) or to a residual water site (≤ 3 km vs ≥ 3 km, crude OR = 1.45) (all p-values < 0.0001). Age distribution analysis showed an older population in the PHS-exposed group. Larger cohorts will confirm our findings.

Facile Synthesis of Chitosan Nanoparticle with Different Features and Histopathological Ultrastructural Study on The Effect of Its Bio-complex with Bovine Serum Albumin in Mice Liver by Maged El-Kemary* in Open Access Journal of Biomedical Science (OAJBS)   We have synthesized chitosan nanoparticles (CS-NPs) with different characteristics using ionic gelation method. Results showed that the synthesized CS-NPs with different concentrations of trisodium polyphosphate (TPP) are irregular – spherical shaped with narrow size distribution and high stability. The microporous chitosan was also synthesized with new features characterized with different techniques as SEM, EDX, FTIR and BET. The synthesized microporous chitosan has a surface area and pore volume of 245.571m 2 /g and 0.155cm 3 /g respectively. Its microporous surface is functionalized with carboxyl and amine groups. Histopathological and ultrastructural studies of mice liver were performed using optical and scanning electron m...

Review on Analysis of Breast Tumor with Methods of Treatment: OAJBS Publishers

Review on Analysis of Breast Tumor with Methods of Treatment by Nagham Mahmood Aljamali* in Open Access Journal of Biomedical Science (OAJBS) Breast malignance is the greatest public in ladies, with a high incidence in North America and Eastern Europe, medium in Southern Europe and the Middle East and low in the Far East. Breast malignance is the second most common malignance in the world after lung malignance, and since it happens a lot, the doctors asked the women to examine themselves by themselves, in order to discover the signs of the disease early before it spreads. It is possible that this disease can be treated after being diagnosed by a specialized doctor and determining the type of tumor in the breast, and the surgeon removes the breast completely and starts chemotherapy about 6 doses, then radiotherapy, how many sessions will be determined by the doctor, and then hormonal therapy, a medicine called Tamoxafin or any medicine determined by the doctor, and it is possible. This ...
