The crude and ethanolic extracts of Curcuma longa L. demonstrate different in vitro cytotoxic effects for the human tumor cell lines DU-145 and HT-29; similar to the standard curcumin compound. The crude extract of Curcuma longa L. shows a potent genotoxic in vitro activity against human genomic DNA; this type of effect is not produced by the ethanolic extract.

To evaluate the capacity of the hyperimmune llama serum (Lama glama) to neutralize the lethal activity of Bothrops atrox venom in laboratory mice.
Mean lethal dose (LD50) was calculated from a Bothrops atrox venom sample pool from Peru. The antibody titers were measured by ELISA assay; and the immune serum neutralization potency was measured by calculating the mean effective dose (ED50) during the immunization period.
The venom's LD50 was 3.96 μg/g; similar to what was found in other studies about Bothrops atrox carried out in Peru. The titers of antibodies against the venom increased rapidly in the llama, demonstrating a fast immune response; however, the neutralization capacity increased slowly and required several doses and immunization reinforcements, obtaining a ED50 of 3.30 μL/g mouse and a neutralization potency of 3.6 mg/mL after 15 immunizations.
The hyperimmune llama serum is able to neutralize the lethality of the Bothrops atrox venom from Peru in laboratory mice.

To estimate the cervical cancer incidence and survival rates by histological subtype and stage in Manizales, Colombia during 2008-2012; and to compare the survival rate to the one from the previous five years.
Using population-based data, incidence rates by age were standardized for each histological subtype. Active and passive follow-up was performed to determine vital status and cause of death at 60 months. The Kaplan-Meier method and Cox models were adjusted to estimate overall survival by each covariant.
A total of 217 new cases were observed; with a mean incidence of 17.8 per 100,000 woman-years. Stages III-IV were more frequently observed in patients of medium and low socioeconomic status. YD23 At 5 years, the survival rate was 68.9%; ages over 70 years were associated with lower survival rates (p<0.001). Risk of death was 90% higher in patients with undifferentiated or unknown histological samples, when compared with those with squamous cell carcinoma (HR 1.9, 95% CI 1.1-3.3). Likewise, the risk of death was 1.7 times higher for patients aged over 70 years (HR 2.7, 95% CI 1.6-4.8); and it was also found to be 3 times higher for stage III (HR 4.3, 95% CI 1.8-10.2) and 7 times higher for stage IV (HR 8.7, 95% CI 3.6-20.1), when compared with stage I.
The incidence rate of cervical cancer in Manizales was found to be similar to the global and continental rates and lower than those from other Colombian cities with similar characteristics. Advanced stages were more frequent in women of low socioeconomic status. Survival was associated with age, histological subtype and staging.

To determine the microbiological quality of samples from processed natural products used for medicinal purposes and marketed in Quito, Ecuador.
Aerobic microorganisms, molds and yeasts were counted by conventional standardized techniques, according to the United States Pharmacopoeia (USP), in samples from 83 products. The microorganisms found were identified and their antimicrobial sensitivity was determined using the agar diffusion method.
The total aerobic microorganism count exceeded the specified limits in 17.0% of syrups, 27.0% of topical products and 43.0% of oral solids; the molds and yeasts count exceeded the limit in 33.0% of syrups, 7.0% of topical products and 36.0% of oral solids. Products for eye use did not pass the sterility test. The most frequently isolated bacterial genus was Bacillus, followed by Escherichia coli, Klebsiella and Enterobacter. Salmonella and Staphylococcus aureus were not found in any product, but potentially pathogenic microorganisms such as Pseudomonas were isolated in 40.0% of the eye drops. Enterobacter and Escherichia coli showed resistance to multiple compounds and Pseudomonas was not resistant to any antibiotic.
The microbiological quality of the products examined was not adequate. Potentially pathogenic and antibiotic resistant microorganisms were isolated from the samples. These products may not be suitable for distribution and consumption, even though many of them have sanitary registration. Control and regulation by the corresponding authorities is essential.

To determine if the place of residence and the level of social marginalization are associated with prostate cancer survival.
All patients diagnosed with prostate cancer (PC) in the period from 2013 to 2017 in a tertiary healthcare hospital in Veracruz, Mexico were included. Patients resided in rural and urban areas. Variables were collected according to clinical-epidemiological and histopathological characteristics. The Kaplan Meier method and the Log Rank test were used to measure survival. Prognostic factors were determined by calculating the adjusted hazard ratio (HRa) in a multivariate analysis using the Cox proportional risk method.
A total of 186 PC cases were analyzed. Overall, after 5 years, 48.3% of the patients survived. Men living in urban areas had a higher probability of survival than those living in rural areas (HRa 1.67, 95% CI 1.16-2.41). Similarly, people living in areas classified as low- marginalization zones had a higher probability of survival than those living in areas with a high level of social marginalization (HRa 2.
