Article Synopsis
  • - Omega-3 fatty acids, particularly EPA and DHA, provide significant health benefits, and research focused on enhancing these acids in fish oil through low-cost methods involving lipase enzymes.
  • - A specific lipase, Lipase F2, derived from the fungus F. solani, was produced using submerged fermentation and demonstrated strong enzyme activity, stability at pH 8.0, and resilience to various conditions.
  • - Lipase F2 effectively enriched fish oil with omega-3 fatty acids, achieving high concentrations of DHA and EPA, making it a cost-effective alternative to commercial enzymes for potential use in the food and pharmaceutical industries.

Background: Chronic low back pain (LBP) is defined as pain lasting longer than 3 months and is one of the conditions with the most significant social impact. Treatment is complex and includes proliferative agents used in prolotherapy. The mechanism is not known, but osmotic agents (hypertonic solutions of dextrose or glucose) cause cellular rupture and an inflammatory response that releases cytokines and growth factors that lead to scarring and reinnervation.

Background: HPV is strongly related to cervical cancer. HPV lineages can contribute to a response to cervical cancer therapy. The aim of this research was to estimate the frequency of human papillomavirus (HPV)-16 lineages in specimens of cervical cancer, relate the pathological factors in these variants, and assess their response to treatment with radical chemoradiotherapy.

(açaí) fruit has approximately 15% pulp, which is partly edible and commercialized, and 85% seeds. Although açaí seeds are rich in catechins-polyphenolic compounds with antioxidant, anti-inflammatory, and antitumor effects-almost 935,000 tons/year of seeds are discarded as industrial waste. This work evaluated the antitumor properties of in vitro and in vivo in a solid Ehrlich tumor in mice.

Human papillomavirus (HPV) infections are associated with cervical cancer and other anogenital cancers. Despite progresses in HPV vaccination and screening, these cancers still show high incidence and mortality, requiring improved prognostic markers and tailored therapies. This review addresses the role of Matrix metalloproteinases (MMPs) in HPV-induced cancers and the modulation of MMP expression by HPV oncoproteins.

Background: Zika virus (ZIKV) is a flavivirus associated with microcephaly and other fetal anormalities. However, evidence of asymptomatic ZIKV infection in pregnant women is still scarce. This study investigated the prevalence of Zika infection in asymptomatic pregnant women attending two public maternities in Maranhão state, Northeast Brazil.

Article Synopsis
  • This study examined how green propolis extract affects the sticking and biofilm formation of Candida species on dental materials.
  • Using high-performance liquid chromatography, researchers identified 15 compounds in green propolis extract, primarily flavonoids, and assessed yeast cell adhesion on materials over time.
  • Results showed that while some Candida species formed moderate to very strong biofilms on materials like steel and resin, green propolis extract effectively inhibited adhesion and biofilm development at a concentration of 2.5 μg/mL, highlighting its potential antifungal properties.

  • This study investigates the antitumoral properties of a fungal extract sourced from a polluted lagoon in Northeastern Brazil.
  • The Ethyl Acetate Extracellular Extract (EAE) was tested on solid Ehrlich tumors in mice, showing significant tumor size reduction across various dosages (4, 20, and 100 mg/kg) while ensuring no harmful side effects.
  • The findings reveal that the extract is rich in meroterpenoids, supports immunomodulation, and suggests that fungal fermentation could be an effective method for developing new antitumor therapies.

Article Synopsis
  • Cardiovascular diseases are major global health issues, and recent research suggests that certain viruses, like HPV, may contribute to the risk of developing coronary artery disease (CAD), especially in women.
  • A study involving 52 climacteric women found that a significant number of those with CAD tested positive for HPV, indicating a strong link between HPV infection and CAD risk.
  • The findings suggest that HPV-positive women have a higher likelihood of having CAD, particularly with high-risk HPV types, but further research is necessary to explore the underlying mechanisms of this association.
