national service, compared with 47% of the patients with implant retention. In total, 186 patients (73.8%) underwent implant removal despite being asymptomatic after the bony union. The patient satisfaction scores improved from 4.1 to 4.4 after implant removal, and 93% of the patients answered that they would choose implant removal again. Only 10% of the patients who underwent removal reported minor complications. No major complications were reported.

Although the implant removal was conducted without clinical symptoms in the majority of patients, overall patients presented improved functional outcomes with implant removal. The evidence is inconclusive regarding its necessity, however, implant removal after VLP fixation for DRF is not a challenging procedure and is not associated with major complications.

To analyze the radiographic and clinical outcomes of deltoid ligament repair, we studied 34 supination external rotation type IV ankle fracture patients with deltoid ruptures who required syndesmosis fixation.

We retrospectively evaluated 34 cases of ruptured deltoid ligaments with associated supination external rotation type IV ankle fractures with a widening of the syndesmosis between 2011 and 2017. All of the ankle fractures were treated with a similar surgical protocol (plate and screw fixation). Syndesmotic fixations were performed on all patients. The deltoid ligaments were surgically repaired in 19 patients and in 15 patients, they were not. The preoperative, immediate postoperative, and final follow-up radiographic outcomes (medial clear space, overlap space, and clear space) and clinical scores (Foot and Ankle Outcome Scores and the Foot Function Index) were compared. Patients were followed for an average of 13.6months.

There was no significant difference in radiographic and clinical outcomes bic reduction could be much more important than deltoid repair in regard to mortise restoration and medial stability.Energy is an essential parameter for the economic growth and sustainable development of any country. Due to the rapid increase in energy demand, depletion of fossil fuels and environmental concerns, many developing and developed countries are moving towards alternative renewable resources such as solar energy, wind energy and biomass. Wind energy as a renewable energy source is gaining a lot of significant attention. Wind energy is a sustainable solution to produce energy having potential benefits such as clean source, reduced toxic gases emission and environmental friendly protocol for operation. Pakistan is among the top countries facing the worst energy crisis due to different political and financial issues. Pakistan is blessed with a huge potential of wind energy having all the basic requirements such as windy regions and good wind speed for harnessing energy. Pakistan can utilize the potential of wind energy to reduce the problem of energy outrage in the country and also take steps towards green economy from conventional fuel economy. This critical review highlights the current status, potential and the steps taken in the past and present to overcome the energy shortage in Pakistan by employing wind energy. Outlook on wind speed data, deployment of wind energy, environmental effect of wind energy and its barriers in the adoption are discussed with recommendations and suggestions to utilize this clean energy in an effective way.

The immune evasion of tumor cells may be the main cause of the difficulties of γδT cell-based treatment. In the present study, we explored whether and how B7-H3 regulates the resistance of CC cells to the cytotoxicity of Vγ9Vδ2 (Vδ2) T cells. We observed that B7-H3 overexpression promoted, while B7-H3 knockdown inhibited, CC cell resistance to the killing effect of Vδ2 T cells in vitro and in vivo. Mechanistically, we showed that B7-H3-mediated CC cell resistance to the cytotoxicity of Vδ2 T cells involved a molecular pathway comprising STAT3 activation and decreased ULBP2 expression. ULBP2 blockade or knockdown abolished the B7-H3 silencing-induced increase in the cytotoxicity of Vδ2 T cells to CC cells. Furthermore, cryptotanshinone, a STAT3 phosphorylation inhibitor, reversed the B7-H3 overexpression-induced decrease in ULBP2 expression and attenuated the killing effect of Vδ2 T cells on CC cells. Moreover, there was a negative correlation between the expression of B7-H3 and ULBP2 in the tumor tissues of CC patients. Our results suggest that the B7-H3-mediated STAT3/ULBP2 axis may be a potential candidate target for improving the efficiency of γδT cell-based immunotherapy in CC.Extracellular glycosyl hydrolases are uncommon in lactobacilli and include amylases and fructosidases mediating starch and fructan utilization, respectively. Extracellular arabinanases have not been described in lactobacilli. This study is aimed at identifying the function of an arabinan utilization operon in Lactobacillus crispatus DSM29598 and at characterizing two putative extracellular arabinanases that are located on that operon. The arabinan utilization operon of L. HIF pathway crispatus DSM29598 encodes enzymes for degradation of arabinan, α-galactosidases, β-galactosidases, and enzymes and for utilization of arabinose including phosphoketolase. The two putative extracellular arabinanases, AbnA and AbnB, are homologous to family GH43 endo-arabinanases. In Lactobacillaceae, homologs of these enzymes were identified exclusively in vertebrate-adapted species of the genus Lactobacillus. L. crispatus grew with arabinan from sugar beet pectin as sole carbon source, indicating extracellular arabinanase activity, and produced lactate and acetate, indicating metabolism via the phosphoketolase pathway. The two arabinanases AbnA and AbnB were heterologously expressed and purified by affinity chromatography. AbnA hydrolyzed linear and branched arabinan, while AbnB hydrolyzed only linear arabinan. The optimum pH for AbnA and AbnB was 6 and 7.5, respectively; 40 °C was the optimum temperature for both enzymes. The application of arabinan degrading L. crispatus as probiotic or as synbiotic with pectins may improve the production of short-chain fatty acids from pectin to benefit host health. KEY POINTS • An arabinan utilization operon in L. crispatus encodes two extracellular arabinanases. • The same operon also encodes metabolic genes for arabinose conversion. • In Lactobacillaceae, extracellular arabinanases are exclusive to Lactobacillus species.
