Background: Normal saline solution (NSS) has been the fluid of choice for renal transplant patients, but it can lead to hyperchloremic acidosis and hyperkalemia. This study was performed to compare the safety profile of low-chloride solutions with that of NSS in renal transplant patients. Methods: We conducted a systemic review search on PubMed, Embase, and the Central Cochrane Registry. Randomized clinical tri-als (RCTs) and matched cohort studies involving NSS as the control arm and low-chloride solutions as an intervention arm were cho-sen. The standardized mean difference for continuous variables, the odds ratio (OR) for discrete variables, and a 95% confidence in-terval (CI) for effect sizes were used. A p-value of <0.05 was considered statistically significant. Analysis was performed using a ran-dom-effects model irrespective of heterogeneity, which was evaluated using I<sup>2</sup> statistics. Results: Nine RCTs and one cohort study with a total of 726 patients were included. After transplantation, serum potassium was sig-nificantly lower in the low-chloride group (standardized mean difference compared to NSS group, -0.38 mEq/L; 95% CI, -0.66 to -0.11; p = 0.007). Similarly, postoperative chloride was lower in the low-chloride group (-2.41 mEq/L [-3.34 to -1.48], p < 0.001). No statistically significance was observed in delayed graft function (OR, 0.98 [0.56-1.69], p = 0.93), day 3 creatinine (-0.14 mg/dL [-0.46 to 0.18], p = 0.38), or day 7 urine output (-0.08 L [-0.29 to 0.12], p = 0.43). onclusion: Use of NSS during renal transplant leads to increased incidence of hyperchloremic acidosis with subsequent hyperkale-mia, but clinical significance in the form of delayed graft function or postoperative creatinine remains comparable to that of low-chlo-ride solutions.

Photorhabdus spp. has a high molecular weight Tc toxin with insecticidal activity. These toxins have been suggested as an alternative to BT toxin from Bacillus thuringiensis. Herein, we constructed a cosmid library with the genome of M1021 and screened the Escherichia coli clones showing insect toxicity by injecting each clone into Galleria mellonella larvae. In a total of 1020 clones, one clone with high insecticidal activity was selected and the nucleotide sequence of the cosmid of the clone was determined. In cosmid PtC28, a gene with 87% homology to the tccB gene of Photorhabdus temperata was found. Consequently, we have isolated the tccB gene cassette from the M1021 and expressed in E. coli expression vectors. The toxin was produced in the form of inclusion bodies but the denatured and refolded recombinant TccB showed strong mortality to the G. mellonella larvae.
