Article Synopsis
- Neoadjuvant chemotherapy (NAC) enhances survival rates in breast cancer patients by improving the rate of pathologic complete response (pCR), but research on blood-based indexes to predict pCR has produced mixed results.
- A study of 304 patients used various blood indexes, including neutrophil-to-lymphocyte ratios (NLR), pan-immune inflammation values (PIV), and lactate dehydrogenase-albumin ratios (LAR), to assess their relationship with pCR and overall survival.
- Results showed that PIV was the most significant predictor of pCR, while a high LAR was associated with increased recurrence risk and poor disease-free survival, revealing crucial insights for breast cancer treatment strategies.
Purpose: To evaluate the effect of a new cross-linked hyaluronan (NCHA) gel on healing of the staple line in an experimental sleeve gastrectomy.
Methods: Eighteen rats were randomly divided into three groups. The control group (n = 6) received no medication.
Appendiceal mucocele is a rare entity which is characterized by cystic dilatation due to abnormal accumulation of mucus in the lumen of the appendix. Patients are often diagnosed incidentally by abdominal screening or abdominal surgery for other causes. Pain in the right lower quadrant of the abdomen, which may present as acute or chronic appendicitis, is the most common symptom of appendix mucocele, when the patient is symptomatic.

Twenty-four female C57BL/6 mice were randomly assigned to four groups, each consisting of 6 mice: a sham group (laparotomy, but no IR injury), a sham + Luteolin group (no IR, and Luteolin was administered intraperitoneally 30 min after laparotomy), IR group (30 min occlusion of the superior mesenteric artery (SMA) then 2 hr' reperfusion), IR + Luteolin (30 min occlusion of the SMA then 2 hr' reperfusion; Luteolin was administered intraperitoneally before reperfusion). Intestine tissues were harvested from the mice for histopathological and biochemical analysis.
