Abstract
Catharina sour, the first internationally recognized Brazilian beer, is characterized by fermentation with lactic acid bacteria (LAB), which may have probiotic potential, and the addition of fruit juice. This study aimed to evaluate the use of the starter Streptococcus thermophilus TH-4 (TH-4) and the probiotics Lacticaseibacillus paracasei F19 and 431, associated with Saccharomyces cerevisiae US-05, in the absence (control)/presence of passion fruit or peach juices. Evaluation proceeded during fermentation and storage by enumeration using pour-plate and qPCR; gene expressions of hop resistance; proteome by Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS); and odor, flavor, and metabolome by Headspace Solid-Phase Microextraction (HS-SPME), coupled with the gas chromatography-mass spectrometry (GC-MS) analysis. We concluded that the strains studied are recommended for applications in sour beers, due to the presence of defense mechanisms like membrane adhesion and H + pump. Furthermore, HS-SPME/GC-MS indicated that the strains may contribute to the beer flavor and odor.

Abstract
Brewer's spent grain (BSG) is a beer industry by-product with interesting functional properties by its high fiber content and bioactive compounds, which may be possibly employed as a prebiotic ingredient. The fermentability of BSG by ten probiotics and two starter cultures was evaluated, and the co-culture of Lacticaseibacillus paracasei subsp. paracasei F-19® (probiotic) and Streptococcus thermophilus TH-4® (starter) was selected to produce a potentially probiotic fermented milk (FM). Four formulations of FM were studied: FM1 (control), FM2 (probiotic - /BSG +), FM3 (probiotic + /BSG -), and FM4 (probiotic + /BSG +). The viability of the microorganisms in the FM was monitored throughout 28 days of storage. The resistance of the microorganisms in the FM to in vitro-simulated gastrointestinal tract (GIT) conditions was also evaluated. Even though the BSG did not influence the fermentation kinetics or increase the populations of both microorganisms in the FM, a significant improvement on the survival of TH-4® against in vitro-simulated GIT stress was observed in the formulations containing BSG alone or in combination with F-19®. All formulations showed potential as probiotic FM, since total probiotic populations were kept above 1010 CFU in a daily portion of 200 mL, and a minimum of 1010 and 108 CFU equivalent of, respectively, TH-4® and F-19® was recovered after the GIT stress. Therefore, TH-4® has potential as a probiotic strain in addition to its starter feature, while BSG may be employed as a possible prebiotic ingredient in a synbiotic approach. Nonetheless, further studies to evaluate possible health benefits are needed.

Abstract
Ovarian cancer (OC) displays the highest mortality among gynecological tumors, mainly due to early peritoneal dissemination, the high frequency of tumor relapse following primary debulking, and the development of chemoresistance. All these events are thought to be initiated and sustained by a subpopulation of neoplastic cells, termed ovarian cancer stem cells (OCSC), that are endowed with self-renewing and tumor-initiating properties. This implies that interfering with OCSC function should offer novel therapeutic perspectives to defeat OC progression. To this aim, a better understanding of the molecular and functional makeup of OCSC in clinically relevant model systems is essential. We have profiled the transcriptome of OCSC vs. their bulk cell counterpart from a panel of patient-derived OC cell cultures. This revealed that Matrix Gla Protein (MGP), classically known as a calcification-preventing factor in cartilage and blood vessels, is markedly enriched in OCSC. Functional assays showed that MGP confers several stemness-associated traits to OC cells, including a transcriptional reprogramming. Patient-derived organotypic cultures pointed to the peritoneal microenvironment as a major inducer of MGP expression in OC cells. Furthermore, MGP was found to be necessary and sufficient for tumor initiation in OC mouse models, by shortening tumor latency and increasing dramatically the frequency of tumor-initiating cells. Mechanistically, MGP-driven OC stemness was mediated by the stimulation of Hedgehog signaling, in particular through the induction of the Hedgehog effector GLI1, thus highlighting a novel MGP/Hedgehog pathway axis in OCSC. Finally, MGP expression was found to correlate with poor prognosis in OC patients, and was increased in tumor tissue after chemotherapy, supporting the clinical relevance of our findings. Thus, MGP is a novel driver in OCSC pathophysiology, with a major role in stemness and in tumor initiation.

Abstract
Amyotrophic lateral sclerosis (ALS) is a severely debilitating disease characterized by progressive degeneration of motor neurons. ALS etiology and pathophysiology are not well understood. It could be the consequences of complex interactions among host factors, microbiome, and the environmental factors. Recent data suggest the novel roles of intestinal dysfunction and microbiota in ALS etiology and progression. Although microbiome may indeed play a critical role in ALS pathogenesis, studies implicating innate immunity and intestinal changes in early disease pathology are limited. The gastrointestinal symptoms in the ALS patients before their diagnosis are largely ignored in the current medical practice. This review aims to explore existing evidence of gastrointestinal symptoms and progress of microbiome in ALS pathogenesis from human and animal studies. We discuss dietary, metabolites, and possible therapeutic approaches by targeting intestinal function and microbiome. Finally, we evaluate existing evidence and identify gaps in the knowledge for future directions in ALS. It is essential to understanding the microbiome and intestinal pathogenesis that determine when, where, and whether microbiome and metabolites critical to ALS progression. These studies will help us to develop more accurate diagnosis and better treatment not only for this challenging disease, but also for other neurodegenerative diseases.

Abstract
Inflammatory bowel disease (IBD) is a chronic inflammation of the gastrointestinal tract (GIT), including Crohn's disease (CD) and ulcerative colitis (UC), which differ in the location and lesion extensions. Both diseases are associated with microbiota dysbiosis, with a reduced population of butyrate-producing species, abnormal inflammatory response, and micronutrient deficiency (e.g., vitamin D hypovitaminosis). Vitamin D (VitD) is involved in immune cell differentiation, gut microbiota modulation, gene transcription, and barrier integrity. Vitamin D receptor (VDR) regulates the biological actions of the active VitD (1α,25-dihydroxyvitamin D3), and is involved in the genetic, environmental, immune, and microbial aspects of IBD. VitD deficiency is correlated with disease activity and its administration targeting a concentration of 30 ng/mL may have the potential to reduce disease activity. Moreover, VDR regulates functions of T cells and Paneth cells and modulates release of antimicrobial peptides in gut microbiota-host interactions. Meanwhile, beneficial microbial metabolites, e.g., butyrate, upregulate the VDR signaling. In this review, we summarize the clinical progress and mechanism studies on VitD/VDR related to gut microbiota modulation in IBD. We also discuss epigenetics in IBD and the probiotic regulation of VDR. Furthermore, we discuss the existing challenges and future directions. There is a lack of well-designed clinical trials exploring the appropriate dose and the influence of gender, age, ethnicity, genetics, microbiome, and metabolic disorders in IBD subtypes. To move forward, we need well-designed therapeutic studies to examine whether enhanced vitamin D will restore functions of VDR and microbiome in inhibiting chronic inflammation.

Abstract
Soymilk was produced from vegetable soybean and fermented by probiotics (Lactobacillus acidophilus La-5, Bifidobacterium animalis Bb-12) in co-culture with Streptococcus thermophilus. The composition of the fermented beverage and oligosaccharides content were determined. The effect of fructooligosaccharides and inulin on the fermentation time and viability of probiotic microorganisms throughout 28 days of storage at 5°C were evaluated. The soymilk from vegetable soybeans was fermented in just 3.2h, when pH reached 4.8. Fermentation reduced the contents of stachyose and raffinose in soymilk. Prebiotics had no effect on acidification rate and on viability of B. animalis and S. thermophilus in the fermented beverage. The viable counts of B. animalis Bb-12 remained above 108CFUmL-1 in the fermented soymilk during 28 days of storage at 5°C while L. acidophilus La-5 was decreased by 1logCFUmL-1. The fermented soymilk from vegetable soybeans showed to be a good food matrix to deliver probiotic bacteria, as well as a soy product with a lower content of non-digestible oligosaccharides.

Abstract
Src homology 2 (SH2) domains are key modules in intracellular signal transduction. They link activated cell surface receptors to downstream targets by binding to phosphotyrosine-containing sequence motifs. The crystal structure of a Grb2-SH2 domain-phosphopeptide complex was determined at 2.4 A resolution. The asymmetric unit contains four polypeptide chains. There is an unexpected domain swap so that individual chains do not adopt a closed SH2 fold. Instead, reorganization of the EF loop leads to an open, nonglobular fold, which associates with an equivalent partner to generate an intertwined dimer. As in previously reported crystal structures of canonical Grb2-SH2 domain-peptide complexes, each of the four hybrid SH2 domains in the two domain-swapped dimers binds the phosphopeptide in a type I beta-turn conformation. This report is the first to describe domain swapping for an SH2 domain. While in vivo evidence of dimerization of Grb2 exists, our SH2 dimer is metastable and a physiological role of this new form of dimer formation remains to be demonstrated.

Abstract
Hepatocyte growth factor (HGF) induces a three-phase response leading to the formation of branched tubular structures in epithelial cells. The HGF receptor tyrosine kinase works through a Src homology (SH2) docking site that can activate several signalling pathways. The first phase of the response (scattering), which results from cytoskeletal reorganization, loss of intercellular junctions and cell migration, is dependent on phosphatidylinositol-3-OH kinase and Rac activation. The second phase (growth) requires stimulation of the Ras-MAP kinase cascade. Here we show that the third phase (tubulogenesis) is dependent on the STAT pathway. HGF stimulates recruitment of Stat-3 to the receptor, tyrosine phosphorylation, nuclear translocation and binding to the specific promoter element SIE. Electroporation of a tyrosine-phosphorylated peptide, which interferes with both the association of STAT to the receptor and STAT dimerization, inhibits tubule formation in vitro without affecting either HGF-induced 'scattering' or growth. The same result is obtained using a specific 'decoy' oligonucleotide that prevents STAT from binding to DNA and affecting the expression of genes involved in cell-cycle regulation (c-fos and waf-1). Activation of signal transducers that directly control transcription is therefore required for morphogenesis.

Abstract
RET/PTC oncogenes, generated by chromosomal rearrangements in papillary thyroid carcinomas, are constitutively activated versions of proto-RET, a gene coding for a receptor-type tyrosine kinase (TK) whose ligand is still unknown. RET/PTCs encode fusion proteins in which proto-RET TK and C-terminal domains are fused to different donor genes. The respective Ret/ptc oncoproteins display constitutive TK activity and tyrosine phosphorylation. We found that Ret/ptcs associate with and phosphorylate the SH2-containing transducer phospholipase Cgamma (PLCgamma). Two putative PLCgamma docking sites, Tyr-505 and Tyr-539, have been identified on Ret/ptc2 by competition experiments using phosphorylated peptides modelled on Ret sequence. Transfection experiments and biochemical analysis using Tyr-->Phe mutants of Ret/ptc2 allowed us to rule out Tyr-505 and to identify Tyr-539 as a functional PLCgamma docking site in vivo. Moreover, kinetic measurements showed that Tyr-539 is able to mediate high-affinity interaction with PLCgamma. Mutation of Tyr-539 resulted in a drastically reduced oncogenic activity of Ret/ptc2 on NIH 3T3 cells (75 to 90% reduction) both in vitro and in vivo, which correlates with impaired ability of Ret/ptc2 to activate PLCgamma. In conclusion, this paper demonstrates that Tyr-539 of Ret/ptc2 (Tyr-761 on the proto-RET product) is an essential docking site for the full transforming potential of the oncogene. In addition, the present data identify PLCgamma as a downstream effector of Ret/ptcs and suggest that this transducing molecule could play a crucial role in neoplastic signalling triggered by Ret/ptc oncoproteins.

Abstract
The equilibrium and kinetic aspects of the interaction between four anthracyclines and two synthetic self-complementary hexanucleotides was investigated by fluorescence detection. Two of the studied anthracyclines are widely used antitumor drugs: doxorubicin (1, formerly adriamycin) and daunorubicin (2, formerly daunomycin). The other two, 9-deoxydoxorubicin (3) and 3'-deamino-3'-hydroxy-4'-epidoxorubicin (4), are doxorubicin analogues with modifications of the chemical groups that have been proposed as responsible for sequence specificity (Chen, K.-X., Gresh, N. and Pullman, B. (1985). J. Biomol. Struct. Dyn. 3, 445-466). One of the oligonucleotides, d(CGTACG), is identical to that used in the high resolution x-ray structure determination of the daunorubicin intercalative complex (Wang, A. H.-J., Ughetto, G., Quigley, G. J. & Rich, A. (1987). Biochemistry 26, 1152-1163). Binding to this hexanucleotide is compared with intercalation into the d(CGCGCG) duplex, revealing sequence preferences of the four anthracyclines. Taking into account the anthracycline aggregation and the dissociation of the hexanucleotide double standard form, results can be interpreted with a model that assumes complete fluorescence quenching at intercalative sites containing the CG base pair, and a large residual fluorescence after intercalation within the TpA fragment. All four anthracyclines show preferential intercalation at sites near the ends of both hexanucleotide duplexes, partly as a result of positive cooperativity in the formation of di-intercalated species at these sites. Within the limits of experimental error, complete site specificity for the CpG fragment is found in the intercalation of 1 and 2 into d(CGTACG) duplex, whereas analogues 3 and 4 give increasing evidence of intercalation at other sites including the fluorescence-preserving TpA fragment. Site specificity is less pronounced in the association with d(CGCGCG), when cooperativity is taken into account. Kinetic data corroborate the results of equilibrium studies and are interpreted with a mechanism that includes formation of an intermediate bound species followed by drug redistribution to preferential sites. Finally, from a comparison of pertinent site binding constants, approximate free energy contributions to sequence specific DNA interaction, due to C9-OH on the aglycone and -NH3+ on daunosamine, are estimated not to exceed 2 kcal/mol.

Abstract
The most efficient routes for the synthesis of FCE 22101, a penem antibiotic characterized by a carbamoyloxymethyl sidechain at C-2 identical to that of cefuroxime and cefotaxime, and of FCE 22891, its orally absorbed pro-drug, are described. On the basis of in-vitro antimicrobial profile and other characteristics the compounds have been considered worthy of further development.

Abstract
The interaction of daunorubicin with the self-complementary DNA fragment d(CGTACG) was studied by 31P NMR spectroscopy. The individual phosphates have been assigned for the nucleotide and the complex and signals from bound and free species in slow exchange at 19 degrees C were detected. In solution, the hexanucleotide binds two molecules of daunorubicin, which intercalate in the d(CG) sequence at both ends of the helix. Evidence for local deformations of the backbone at the sites of C5pG6, C1pG2 and G2pT3 phosphates is given. The binding constants for the stepwise equilibrium and the rate of dissociation of the intercalated duplex were also determined.

Abstract
1 Twenty-four patients suffering from severe pain due to chronic occlusive arterial disease of the legs were given oral doses of indoprofen (200 mg), ibuprofen (300 mg) and placebo. 2 Differences in pain intensity scored on a five-point scale were taken as measurement of pain relief. 3 This double-blind, cross-over trial showed that indoprofen had significantly greater analgesic effect than placebo and reference drug. 4 From a methodological point of view there are many arguments on favour of pathological ischaemic pain as a test for clinical assessment of analgesics.

Abstract
In a group of 129 female patients with nodular goiter, Graves' disease and primary hypothyroidism, the PRL and TSH secretions were studied in parallel. Concurrent changes in the two hormones were evident only in conditions of marked hyper- or hypothyroidism. In the patients with non-toxic nodular (single or multiple) goiter the TSH showed low or normal values, while the PRL appeared normal or elevated. From these results two important conclusions can be drawn: 1. the T3 and T4 levels interact with PRL secretion concomitantly with TSH only when they undergo a huge deviation from the normal range; 2. the goitrogenic action of PRL that has been reported in experimental animals cannot be excluded in man.

Abstract
During cholecystectomy 21 patients were subjected to transcystic extraction of common bile duct stones by a Dormia-Pironneau catheter; this was the only treatment used for lithiasis of the common bile duct, in the absence of papillary lesions. Of these patients, 14 were followed up from one to three years after surgery. Clinical and radiological controls revealed the patients' complete recovery from the biliary disease. Our late results thus warrant the method. We suggest that is should be employed in all cases in which the presence of minute stones in the gallbladder, a wide cystic duct, and the absence of papillary lesions suggest migration of gallstones from the gallbladder to the common bile duct.

Abstract
1. Phenylethane-1,2-diol 2-acetate has been isolated from the incubation of styrene oxide or styrene diol with liver microsomes of phenobarbital-pretreated rabbits. 2. Observed ratios of phenylethane-1,2-diol to its 2-acetate in the incubation mixtures ranged between 19 : 1 and 5 : 1 with different microsomal preparations and different periods of incubation. 3. The formation of phenylethane-1,2-diol 2-acetate may be a source of errors in the radiometric determination of epoxide hydrase activity in microsomes.

Abstract
With a view to carrying out a critical review of the use of instrumental divulsion in surgery of the bile ducts, a long-term follow-up was made, from one to 12 years after performance of this operation, in 103 out of 157 cases. An examination of the immediate results which were favourable, in contrast with those found at long-term, led to the conclusion that this procedure was of little use and it has now been dropped both in diagnostics and, with greater reson, in treatment of benign papillary stenosis.
