Newly Discovered Dinosaur Species Looks Like Something Dr. Seuss Dreamed Up

(WASHINGTON) — With a bill like a duck but teeth like a croc’s, a swanlike neck and killer claws, a new dinosaur species uncovered by scientists looks like something Dr. Seuss could have dreamed up. It also had flippers like a penguin, and while it walked like an ostrich it could also swim. That’s the first time swimming ability has been shown for a two-legged, meat-eating dinosaur. The tiny creature, only about 18 inches (45 centimeters) tall, roamed 75 million years ago in what is now Mongolia. Its full curled-up skeleton was found in a sandstone rock. “It’s such a peculiar animal,” said Dennis Voeten, a paleontology researcher at Palacky University in the Czech Republic. “It combines different parts we knew from other groups into this one small animal.” In a study released Wednesday by the journal Nature, Voeten and coauthors named it Halszkaraptor escuilliei (HAHL-shka-rap-tor ES-key-lay-ee) or “Halszka” after the late Polish paleontologist Halszka Osmolska. Paleontologist Kristi Curry Rogers of Macalester College in St. Paul, Minnesota, who didn’t participate in the study, called it “a pretty crazy chimera: a swan neck and dinosaur body, but with a mouthful of tiny teeth and hands and feet that look like they might be good for swimming.” Its mashup body let it run and hunt on the ground and fish in fresh water, said study co-author Paul Tafforeau. He’s a paleontologist at the ESRF, known...

This study compared the effects of different dietary energy contents (11.3, 12.0 and 12.7 MJ ME/ kg feed) fed ad libitum in a feedlot on the carcass quality characteristics (carcass yield, commercial yield, 3-rib cut) of goats introduced to feedlot at 22.2 ± 3.5 kg (18 weeks of age), and slaughtered at five week intervals. The energy content of the finisher diets had no effect (P > 0.05) on any of the traits measured. However, the time spent in the feedlot influenced (P

Conclusions: B cells and NK cells closely correlate with patients' condition and may help to diagnose AP more accurately and reflect treatment effect of AP in time, affecting the recovery speed of patients with M-AP, which may help physicians to better understand the pathophysiology of pancreatitis.

In this study, MHC-1 and PDL-1 score in primary and metastatic tumor cells was evaluated in 43 gastric cancer patients with lymph node metastasis. According to our results, the primary tumor PDL-1 score was correlated with the number of metastatic lymph nodes (r = 0.258; p = 0.024) and primary tumor size (r = 0.341; p = 0.045). A similar correlation was found between the primary tumor PDL-1 score and the metastatic tumor PDL-1 score (r = 0.213; p = 0.015). In our study, MHC-1 was found to be higher in primary tumors than metastatic tumors, although not statistically significant (p = 0.054). The results of our study showed ...

Conclusion: EA and MB were able to regulate the concentration of CRH in serum and protein expression in the peripheral and central at different levels and promote the recovery of the HPA axis that may be the basis for EA and MB to improve colonic pathology and alleviate anxiety behavior in DSS-induced colitis.

Authors: McCarthy AJ, O'Reilly SM, Shanley J, Geraghty R, Ryan EJ, Cullen G, Sheahan K Abstract Background: As the malignant potential of sessile serrated lesions/polyps (SSL/Ps) and traditional serrated adenomas (TSAs) has been clearly demonstrated, it is important that serrated polyps are identified and correctly classified histologically. Aim: Our aim was to characterize the clinicopathological features of a series of SSL/Ps &TSAs, to assess the accuracy of the pathological diagnosis, the incidence, and the rate of dysplasia in SSL/Ps &TSAs. Methods: We identified all colorectal serrated polyps b...

Based on a detailed review of published literature, a deterministic simulation model was constructed using the escalator box-train approach, which allows for fully-overlapping cohorts of worms and approximately normally distributed variations in age/size classes. Key biological features include a declining establishment of ingested infective stage larv...
