Using a Holliday-junction-like scrambling mechanism, also analogous to DNA, rings may be manipulated (increased, decreased, exchanged) easily with little to no need for additional energy, the reaction being essentially an isomerization.A literature review is presented describing findings that support the above hypothesis. Reviewed is condensed phosphate inorganic chemistry including its geological origins, biological occurrence, enzymes and their genetics through eukaryotes, polyphosphate functions, circular polynucleotides and the role of the Holliday junction, previous biogenesis hypotheses, and an Eoarchean Era timeline.There are numerous advantages of splenic vessel preservation in performing the minimally invasive spleen preserving distal pancreatectomy. Dissection along the splenic artery, and a medial to lateral dissection of the splenic vein, is associated with high risk of injury and bleeding. Proximal control of the splenic artery with vessel loops, which require tightening or adjustment with the advent of distal bleeding, is inefficient. Instead, a modified technique (the Royal North Shore Technique), whereby a vascular clamp is placed on the splenic artery, reduces splenic artery inflow and indirectly, splenic vein returns. This allows for more accurate and injury-free dissection of the now non-distended splenic vein and the associated tributaries, and maintains a relatively bloodless field in the event of arterial injury.

Laparoscopic pancreaticoduodenectomy (LPD) is a technically demanding procedure that is considered safe and feasible if performed in a high-volume institution, where surgeons and medical staff is appropriately trained. For this advanced abdominal procedure only few studies described a reproducible stepwise technique and a standard approach is still lacking.

The attached video reports all steps of our standardized LPD with pancreatojejunal and hepatojejunal anastomotic stent placement performed with a double approach. The laparoscopic demolitive phase, exactly as the laparotomic one, begins with the surgeon placed on the patient’s right side, while for the reconstructive one he moves between the patient’s legs. The main characteristic of this technique is an easy realization of the end-to-side biliary anastomosis with a Kehr’s “T” tube segment placement as internal biliary stent. This easy technical tip can facilitate the anastomosis realization that remains the most challenging step of this laparoscopic technique, especially in case of small common bile duct.

We consider that our standardized technique can be safely performed and it can facilitate the anastomosis execution, especially the hepatic-jejunal.

Despite our reproducible stepwise technique could help to minimize the learning curve for LPD, further randomized controlled trials are needed to validate the superiority of minimally invasive approach.

Microbiota has crucial biological importance for human well-being. Bidirectional interaction exists between microbiota and the host, and there have been no studies investigating this interaction in patients with acromegaly. We aimed to analyze the composition of microbiota in patients with newly diagnosed acromegaly.

Stool samples were obtained from the patients with newly diagnosed acromegaly in the Endocrinology Clinic of Erciyes University Medical School. The composition of microbiota was analyzed, and the results were compared to healthy volunteers matched to the patients in terms of age, gender and body mass index.

Seven patients (three male, four female) with a mean age of 48 ± 17.6 years were included in the study. The stool analysis revealed a significantly lower bacterial diversity in the patients with acromegaly. Bacteroidetes phylum was predominating in the patient group, and Firmicutes/Bacteroidetes ratio was altered significantly. Bifidobacterium, Collinsella, Bacteroides, Butyricimonas, Clostridium, Oscillospira, and Dialister were predominating in the control group.

The gut microbiota is significantly altered in patients with newly diagnosed acromegaly. Further prospective studies are needed to elucidate the causative relationship between acromegaly, colorectal pathologies, and microbial alterations.

We relied on an observational cohort study, based on data from 1988 to 2018, including 857 Roman Catholic bishops, 500 Catholic priests, and 3038 male academics from six countries. We measured the covariance of the mean length of life, controlled for nationality. It was found that there is a main effect for occupation F(2, 4391) = 4.07, p = 0.017, ηp2 = 0.002, with pairwise comparisons indicating significant differences between the mean life duration of bishops (M = 30,489) and of priests (M = 29,894), but none between the academic teachers (M = 30,147) and either of the other groups. A comparison analysis between bishops from the largest and the smallest dioceses showed no significant difference t(67.31) = 1.61, p = 0.11. The first analysis proved that bishops live longer than priests, but due to a marginal effect size this result should be treated with caution. No difference was found between the mean length of life of bishops from the largest and the smallest dioceses.

Fibroblast activation protein-α (FAPα) is uniquely expressed in activated fibroblasts, including cancer-associated fibroblasts that populate tumor stroma and contribute to proliferation and immunosuppression. Radiolabeled FAPα inhibitors enable imaging of multiple human cancers, but time-dependent clearance from tumors currently limits their utility as FAPα-targeted radiotherapeutics. We sought to increase the area under the curve (AUC) by constructing a trifunctional ligand that binds FAPα with high affinity and also binds albumin and theranostic radiometals.

RPS-309 comprised a FAPα-targeting moiety, an albumin-binding group, and 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA). Inhibition of recombinant human FAPα (rhFAPα) was determined by colorimetric assay. Affinity for human serum albumin (HSA) was determined by high-performance affinity chromatography. The tissue distribution of [

Ga]Ga-RPS-309 in SW872 tumor xenograft-bearing mice was imaged by microPET/CT and quantified by biodistribution studies performed from 30 min to 3 h post injection (p.
