RESUMEN

Objective: To identify the efficacy and tolerability of Proteoglycan F in patients with primary knee OA.Design: A 24-week randomized, placebo-controlled, double-blind clinical trial with two arms: (1) Proteoglycan F (received 10 â€‹mg proteoglycan daily, for 24 weeks) and (2) control group (received placebo). Knee symptoms and joint cartilage status (evaluated by ultrasound and MRI of knee joints), quality of life, serum cytokine levels (IL-1ß and TNF-α), and safety evaluation were measured before, during, and after the treatment. Results: After 24-week treatment, pain reduction (in the KOOS pain score) of at least 20% and at least 50% (NRS scale) compared to baseline in the PGF group was significantly higher than those in the control group. The PGF group had greater reductions in the total scores of subchondral bone marrow edema, and bone cocoon under cartilage on knee MRI (classification according to WORMs), which were -2.27 (-4.0; -0.51) and -1.77 (-3.08; -0.46), respectively (p â€‹< â€‹0.05). The two groups had no statistically significant difference in knee ultrasound characteristics. After 4 weeks, 12, and 24 weeks compared to baseline, there was no statistically significant difference in levels of urea, creatinine, aspartate aminotransferase, and alanine aminotransferase within the group and between the two study groups. Conclusions: Salmon cartilage PG with 10 â€‹mg per day has potential to improve pain symptoms and subchondral bone marrow edema and bone cocoon under cartilage lesions in primary knee OA. However, the efficacy of PGF should be viewed with caution, and future studies are needed for more specific evaluation.

RESUMEN

The cicada species, Hyalessa fuscata and H. maculaticollis(Hemiptera: Cicadidae), share numerous morphological characters, and their status as distinct species remains controversial. We reconstructed a phylogeny based on two new mitogenomes of H. fuscata from Korea and H. maculaticollis from Japan, in combination with GenBank sequences of H. maculaticollis from China and Japan, and other closely related cicada species. Maximum likelihood and Bayesian inference phylogenies showed that H. fuscata from Korea is more closely related to H. maculaticollis from China than either is to H. maculaticollis from Japan. The time-calibrated Bayesian evolutionary analysis by sampling trees (BEAST) phylogeny indicated that the mainland and insular forms diverged approximately 1.7-2.6 million years ago. This coincides with the formation of the East China Sea land bridge between East Asia and the Japanese archipelago, which would provide a dispersal corridor for Hyalessa from the mainland via the Korean peninsula southeastward to Japan. East Asian H. fuscata is a geographic variant that may be considered synonymous with H. maculaticollis.

RESUMEN

CD47 is a cell surface glycoprotein molecule, belonging to the immunoglobulin superfamily, binding to various proteins including integrins, thrombospondin-1, and signal regulatory protein α (SIRPα). CD47 is an important tumor antigen for the development and progression of various cancers. This study designed the chimeric antigen receptor T-cell (CAR-T) to bind to the CD47 to inhibit the expression of CD47. We used the complementarity-determining regions (CDRs) of the B6H12 mouse antibody grafted onto the IgG1 framework to create the humanized single-chain variable fragment (scFv) with linker (G4S)x3. scFv was used to design the chimeric antigen receptor with the structure CD8signal-CD47scFv-CD8a hinge-CD4TM-CD28-41BB-CD3ζ, which was then transformed into T lymphocytes by the lentivirus to create third generation of CAR-T. Results revealed that the new CAR-T cells efficiently killed A549 cancer cells. CAR-T inhibited the expression of genes involved in metastasis and invasion of cells A549 including beta actin, calreticulin, and cyclooxygenase 2 at mRNA levels.

RESUMEN

OBJECTIVE: This study aimed to perform the reverse-transcription polymerase chain reaction (RT-PCR) to express the survivin mRNA among patients with breast cancer in Vietnam and identify some potential associated clinical and pathological factors. METHODS: Peripheral blood (PB) samples and tissues on 43 patients with breast cancer and 21 patients with fibroids were obtained. The Real-time RT-PCR and gene sequencing techniques were employed to detect survivin gene in breast cancer cell lines and cancer tissues. RESULTS: Survivin mRNA transcription was detected in 32/43 (74,4%) of breast cancer tissues and 19/43 (44,2%) of PB samples of breast cancer patients, while it was detected in only 14,3 % fibrosis tissues and 0% in the blood of fibrosis patients. Survivin mRNA on the peripheral blood of breast cancer patients increased with tumor size, and stage of cancer (p < 0.05). In terms of breast cancer tissue, no difference was found in the rate of survivin mRNA expression in according to age, distant metastasis, lymph node, stages of cancer, and histopathology (p > 0.05). CONCLUSIONS: Results provide the initial evidence of the expression of survivin mRNA in breast cancer patients in Vietnam, suggesting the role of survivin mRNA in breast cancer molecular pathology.

RESUMEN

Two studies were conducted to evaluate the effects of dietary supplementation of guanidinoacetic acid (GAA) on growth performance, carcass characteristics, and meat quality in pigs from wean to finish (Exp 1) and finishing pigs fed GAA at different time periods before slaughter (Exp 2). In Exp 1, a total of 360 weaned pigs (Duroc × [Landrace × Yorkshire]) with an average initial BW of 7.17 ± 0.03 kg were randomly distributed into 3 dietary treatments consisting of 10 replicates per treatment and 12 pigs (6 barrows and 6 gilts) per replicate. Dietary treatments were a control (CON; basal diet), a basal diet + 0.08% GAA (0.08% GAA); and a basal diet + 0.12% GAA (0.12% GAA). The duration of the experiment was 150 d. At the end of the experiment, 20 pigs (10 barrows and 10 gilts) from each treatment were slaughtered for measuring carcass characteristics and meat quality. In Exp 2, 1,440 finishing pigs [(Duroc × (Landrace × Yorkshire)), 56.15 ± 0.10 kg BW)] were randomly allocated to 4 treatments with 18 replicates (20 pigs per replicate). Dietary treatments were a control diet (CON; basal), a basal diet + 0.12% GAA fed 60 d before slaughter (T1), a basal diet + 0.12% GAA fed 40 d before slaughter (T2), and a basal diet + 0.12% GAA fed 25 d before slaughter (T3). Body weight was measured at the start (120 d of age) and at the end (180 d of age) of the experiment. At the end of the study, 144 pigs (72 barrows and 72 gilts) from 4 dietary treatments (36 pigs per treatment) were slaughtered for the determination of carcass and meat quality parameters. In Exp 1, 0.12 % GAA increased (P < 0.05) ADG and G:F during starter, grower, finisher, and the overall growth period (30 to 180 d of age). Pigs fed 0.12 % GAA had improved (P < 0.05) lean meat yield in comparison with CON. There was no interaction effect among GAA supplementation and sex of the pigs. Meat quality was not affected by GAA supplementation in pigs. In Exp 2, the final BW, ADG, and lean yield of the pigs fed T1 were higher (P < 0.05) than CON and those fed T3. The carcass back-fat thickness of T1 was lower (P < 0.05) than CON. In conclusion, 0.12% GAA improved the growth performance and lean meat yield in pigs from wean to finish. Finishing pigs fed diets supplemented with 0.12% GAA 60 d before slaughter improved ADG, feed efficiency, and lean meat yield and reduced back-fat thickness compared with those fed GAA unsupplemented diets.
