Nutrient colimitation is a quantitative, dynamic property of microbial populations.

Resource availability dictates how fast and how much microbial populations grow. Quantifying the relationship between microbial growth and resource concentrations makes it possible to promote, inhibit, and predict microbial activity. Microbes require many resources, including macronutrients (e.

Management of a Rare Case of Superior Mesenteric Artery Aneurysm Associated with a Pancreatic Cyst Complicated by Acute Rupture: A Case Report and Review of Literature.

Superior mesenteric artery aneurysms are a rare pathology, and rupture due to a pancreatic cyst in the context of alcohol-induced pancreatitis is an even rarer condition. The first line of treatment is usually an endovascular approach. We present the case of a 51-year-old male with alcohol-induced pancreatitis, diagnosed with a superior mesenteric artery aneurysm with active bleeding in close contact with a large pancreatic cyst.

The Predictive Value of Perioperative Inflammatory Indexes in Major Arterial Surgical Revascularization from Leriche Syndrome.

The role of inflammation in the pathophysiology of atherosclerosis is extensive. Our study aims to assess the predictive role of inflammatory indexes regarding in-hospital mortality in major vascular surgery of Leriche syndrome as a convenient, low-cost, and noninvasive prognostic marker to optimize the patient's perioperative course. : Our retrospective single-center study enrolled consecutive patients diagnosed with aortoiliac occlusive disease, Leriche syndrome, who underwent elective major vascular surgery between 2017 and 2023 in a tertiary cardiovascular center.

A Review of Contemporary Image Guidance Techniques in Head and Neck Cancer.

Background: Traditional head and neck cancer treatment involves open surgery, cytotoxic chemotherapy, and conventional radiotherapy planning. Emerging techniques aim to improve precision and reduce associated toxicity and functional impairment in current practice. This review article describes four such adaptations in image guidance, tailored to next generation therapies.

Ultrasound-guided intra-tumoral administration of directly-injected therapies: a review of the technical and logistical considerations.

Background: Directly-injected therapies (DIT) include a broad range of agents within a developing research field in cancer immunotherapy, with encouraging clinical trial results in various tumour subtypes. Currently, the majority of such therapies are only available within clinical trials; however, more recently, talimogene laherparepvec (T-VEC, Imlygic) has been approved as the first oncolytic virus therapy in the USA and Europe. Our institution contributes to multiple different trials exploring the efficacy of DIT, the majority of which are performed by oncologists in clinic.
