Cryopreservation of ovarian tissue: the biggest challenge of oncofertility.

Survival rates after cancer diagnosis and treatment have been raising through the last decades. Nowadays, oncofertility represents a useful strategy for young women affected by cancer to preserve their ovarian function and their family planning opportunity. Apart from more diffused techniques as cryopreservation of mature oocytes after controlled ovarian stimulation and gonadal downregulation with gonadotropin-releasing hormone agonist depots, the cryopreservation of the cortical region of the ovarian tissue, which contains 90% of the follicular reserve, and later autologous transplant represent a possible and intriguing strategy.

Bisphenol A-Induced Epigenetic Changes and Its Effects on the Male Reproductive System.

Bisphenol A (BPA) is a widespread chemical agent which can exert detrimental effects on the male reproductive system. Exposure to BPA has been shown to induce several epigenetic modifications in both animal and human cells. Specifically, BPA could not only modify the methylation pattern of multiple genes encoding proteins related to reproductive physiology but also directly influence the genes responsible for DNA methylation.

Liposome-Embedding Silicon Microparticle for Oxaliplatin Delivery in Tumor Chemotherapy.

Mesoporous silicon microparticles (MSMPs) can incorporate drug-carrying nanoparticles (NPs) into their pores. An NP-loaded MSMP is a multistage vector (MSV) that forms a Matryoshka-like structure that protects the therapeutic cargo from degradation and prevents its dilution in the circulation during delivery to tumor cells. We developed an MSV constituted by 1 µm discoidal MSMPs embedded with PEGylated liposomes containing oxaliplatin (oxa) which is a therapeutic agent for colorectal cancer (CRC).

The Treatment of Hypersalivation in Rett Syndrome with Botulinum Toxin: Efficacy and Clinical Implications.

Introduction: Subjects with Rett syndrome (RS) develop invariably severe motor deterioration resulting in swallowing difficulties that may produce excessive drooling. Hypersalivation can cause discomfort due to hygienic problems and may complicate with oral and respiratory dysfunctions. The aim of this study is to evaluate the response to treatment with botulinum toxin (BTX) for hypersalivation and to identify possible benefits of saliva reduction on oral motor and respiratory disorders of patients with RS.

Improved reference genome of Aedes aegypti informs arbovirus vector control.

Female Aedes aegypti mosquitoes infect more than 400 million people each year with dangerous viral pathogens including dengue, yellow fever, Zika and chikungunya. Progress in understanding the biology of mosquitoes and developing the tools to fight them has been slowed by the lack of a high-quality genome assembly. Here we combine diverse technologies to produce the markedly improved, fully re-annotated AaegL5 genome assembly, and demonstrate how it accelerates mosquito science.

Improvement of Bone Physiology and Life Quality Due to Association of Risedronate and Anastrozole.

The endocrine therapy is the new frontiers of many breast cancers hormone sensitive. Hormone therapy for treating women with hormone receptor-positive cancer suppresses breast cancer growth either by reducing estrogen synthesis or by interfering with the action of estrogen within tumor cells. In this prospective randomized observational study we investigate the effect of adjuvant anastrozole in monotherapy or associated with risedronate on bone physiology and quality of life in postmenopausal, hormone-sensitive early breast cancer women at mild to moderate risk of fragility fractures.

Long-read, whole-genome shotgun sequence data for five model organisms.

Single molecule, real-time (SMRT) sequencing from Pacific Biosciences is increasingly used in many areas of biological research including de novo genome assembly, structural-variant identification, haplotype phasing, mRNA isoform discovery, and base-modification analyses. High-quality, public datasets of SMRT sequences can spur development of analytic tools that can accommodate unique characteristics of SMRT data (long read lengths, lack of GC or amplification bias, and a random error profile leading to high consensus accuracy). In this paper, we describe eight high-coverage SMRT sequence datasets from five organisms (Escherichia coli, Saccharomyces cerevisiae, Neurospora crassa, Arabidopsis thaliana, and Drosophila melanogaster) that have been publicly released to the general scientific community (NCBI Sequence Read Archive ID SRP040522).
