This study aimed to enhance the crystallizability of bio-based succinic acid for its efficient recovery while maintaining the end product at the highest purity. Masitinib Immobilization of Actinobacillus succinogenes was initially evaluated based on three different carriers volcanic glass, clay pebbles, and silica particles. The adsorption capacity of metabolites with a low concentration (10 g/L) and a high concentration (40 g/L) was investigated. It was demonstrated that clay pebbles adsorbed the least succinic acid ( less then  11 mg/g clay pebbles). The repeated batch-fermentation trials with immobilized cells highlighted that succinic acid with an average concentration of up to 36.3 g/L with a metabolite-production ratio of 31 (succinic acid to by-products) could be attained within 130 h. Subsequently, the purification of succinic acid through crystallization was assessed in terms of pH, temperature, crystallization time, initial succinic acid concentration and multiple recrystallization processes. Increasing the crystallization time from 6 h to 9 h afforded an improvement of 17% in the recovery of succinic acid crystals. Moreover, a fourfold concentration coefficient of the broth yielded the highest purity percentage (99.9%). The crystallization in three consecutive stages at 9 h (with a fourfold concentration coefficient) successfully improved the total recovery percentage of succinic acid from 55.0 to 84.8%.This paper details the first breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) case detected in Japan. The patient, a 67-year-old Japanese woman, was diagnosed with left unilateral breast cancer 17 years ago. Induration and redness presented in the left breast, which had undergone immediate breast reconstructive surgery using a tissue expander, later replaced by a silicone breast implant (SBI). Breast ultrasound showed fluid collection around the SBI. Surgery was performed to remove the left breast implant and the fragmented capsule surrounding the implant. Postoperative pathological findings did not indicate malignancy. Nine months later, a contralateral axillary lymphadenopathy was observed, and an excisional biopsy of the axillary lymph node was performed. The patient was diagnosed with BIA-ALCL and successfully underwent adjuvant CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) chemotherapy.INTRODUCTION Short-chain fatty acids (SCFAs) are ubiquitous lipids produced as a result of bacterial fermentation of dietary fiber. While their role in colorectal cancer is well known, the effect of SCFAs in breast cancer is poorly defined. OBJECTIVE To understand the various effects of SCFAs on breast carcinogenesis, we investigated the effect of sodium butyrate (NaB) and sodium propionate (NaP) in MCF-7 cell line. MATERIALS AND METHODS Cells were incubated with different concentrations of NaB or NaP for 24, 48, 72 or 96 h. Cell proliferation was assayed using MTT kit. Cell cycle was performed using propidium iodide staining then analyzed with a flow cytometer. Apoptosis was assessed by Hoechst technique and cell-cycle sub-G1 phase. RESULTS NaB and NaP inhibited MCF-7 cell proliferation in a dose-dependent manner with respective IC50 of 1.26 mM and 4.5 mM, thus indicating that NaB is more potent than NaP. Low and medium levels of both SCFAs induced morphology changes which are characteristic of a differentiated phenotype. Flow cytometry analysis revealed a blockage in G1 growth phase. Interestingly, removing NaB or NaP from culture media after few days of treatment showed a reversible effect on cell morphology and proliferation where cells reentered the cycle after 24 h of drug wash-out. Finally, treatment with medium levels of these molecules induced low MCF-7 apoptosis, while higher doses led to massive apoptosis. CONCLUSION Our results show that SCFAs may be considered as an interesting inhibitor for breast cancer progression.The fan mussel, Pinna nobilis is a highly endangered bivalve species endemic to the Mediterranean Sea. During the last few decades, populations have been greatly reduced due to anthropic impacts and they are now under strict protection in most Mediterranean countries. Today, the species is facing a major crisis following the introduction of an haplosporidan parasite which is driving mass mortality in almost all P. nobilis populations throughout the Mediterranean Sea. Gathering additional knowledge regarding dynamics and connectivity patterns of P. nobilis populations is now more than ever critical. Here, we describe the development of 26 highly polymorphic microsatellite markers. Average allelic diversity of 10.9 alleles per locus was reported and heterozygosity ranged from 0.0294 to 0.9737. We tested cross-species amplification in four Pinna species for the new markers together with 10 already published markers, and analysed its success according to the genetic distances among species. Cross-species transferability success ranged from 3 to 38% and had a negative relationship with the genetic distance between the target species and the tested species. The establishment of this new set of high-resolution markers provides a useful tool to understand processes driving gene flow and genetic diversity in P. nobilis populations and the closest congeneric species.Two new cytotoxic 1,8-naphthalimide derivatives have been synthesized and characterized. Their biological activities as cytotoxicity and antimicrobial activities and inhibitory activities against DNA-polymerase were evaluated. The interactions of compounds with double-stranded- and quadruple-DNA have been studied by UV-Vis, fluorescent intercalator displacement, competition dialysis, circular dichroism and the findings were compared with the parent naphthalimide and the other compounds. The results show that both compounds (1 and 2) and the parent compound NI have strong cytotoxic activities against Beas-2B, MCF-7, HepG2 and MDA-MB-231 cancer cell lines, antimicrobial activities against Staphylococcus aureus ATCC 29213, Enterococcus faecalis ATCC 29212 and inhibitory activities towards Taq-polymerase and transcriptase. These novel cationic compounds 1 and 2 can stabilize G-quadruplexes DNA according to thermal denaturation experiments, they change the 3D structure of the DNA (see details in CD experiments) and they exhibit different binding affinities for q-DNA and ds-DNA revealed by spectrophotometric titrations and competitive dialysis studies.
