An Ecological Assessment of a Juvenile Estuarine Sportfish, Common Snook (Centropomus undecimalis), in a Tidal Tributary of Tampa Bay, Florida
No full textThe common snook, Centropomus undecimalis, is an estuarine dependent sport fish that relies upon subtidal wetlands as nursery habitat. Despite the economic and recreational significance of this species, there are portions of its life history and biology that are poorly understood, particularly its early life history. Understanding juvenile snook use of wetland habitats is crucial given the rapid loss and degradation of these areas to anthropogenic impacts. Young-of-the-year snook were collected in pond and creek habitats of a single wetland system to assess early life ecology and habitat use. Proxies of habitat quality were used to determine which habitats within a small spatial scale were optimal for young-of-the-year snook recruitment. Results indicated that even on a very small spatial scale, differences in habitat use were apparent, whereby smaller snook initially recruited to pond habitats and dedicated all energy into growth. Upon reaching a size of at least 40 mm SL snook began an ontogenetic habitat shift and moved to the tidal creek habitat. There, snook began to store energy, thus becoming more robust. Stable carbon and nitrogen isotopic analyses confirmed the ontogenetic habitat shift and revealed that snook have high site fidelity within the pond and creek habitats. Stable isotopic analysis also indicated that YOY snook appear to feed at the third trophic level consuming neonatal poecilliids and shrimp, and ultimately rely on benthic microalgae and particulate organic matter as basal resources. Results of this study advance the knowledge of juvenile snook ecology and will likely have implications for resource managers who are responsible for preserving and restoring wetland habitats upon which juvenile snook rely
Site Fidelity and Condition Metrics Suggest Sequential Habitat Use by Juvenile Common Snook
No full textThe common snook Centropomus undecimalis is an estuarine-dependent fish that relies on landward wetlands as nursery habitat. Despite its economic importance, portions of the snook’s early life history are poorly understood. We compared habitat use of young-of-the-year (YOY) snook in 2 geomorphic mesohabitats (tidal pond and tidal creek) along an estuarine gradient (upstream vs. downstream) within a single wetland during fall recruitment. We used abundance, length, condition indices, and stable isotopes to assess ontogenetic mesohabitat use and site fidelity. We found that (1) YOY snook were more abundant within the upstream creek and ponds; (2) the smallest snook were found only in ponds; (3) snook from ponds had lower condition (Fulton’s K and hepatosomatic index); (4) snook began moving from ponds to the creek at ~40 mm standard length; and (5) snook from the 2 mesohabitats were isotopically distinct, indicating high site fidelity at rather small spatial scales. Collectively, these data identified sequential use of mesohabitats, wherein seaward-spawned YOY snook moved landward and recruited to pond habitats, where they dedicated energy to growth (as length) before making an ontogenetic habitat shift to the creek. Once in the creek, YOY snook condition improved as they approached maturity and started the downstream return towards seaward locations. The wetland network that was previously viewed as generalized nursery habitat instead consists of mesohabitats that support different life stages in sequence. This represents ontogenetic habitat complementation, in which lower availability of a required mesohabitat type may limit the entire wetland’s contribution to the adult population
Rib/snook design in mechanised depillaring of rectangular/square pillars
No full textThis is the author accepted manuscript. The final version is available from Elsevier via the DOI in this record.A field study at different mechanised depillaring (MD) operations in Indian coalfields (with depth ranging from 60 to 377 m and caveability Index variation from 2300 to 10500) found mixed performances of adopted sizes of the ribs/snooks. Formation of an irregular shaped rib/snook during MD of the existing square/rectangular pillars by a continuous miner and uniqueness of the existing geo-mining conditions limit scope of application of the conventional rib/snook design approaches. Taking guidance from the field studies, a parametric investigation is conducted in laboratory on the calibrated simulated models using FLAC3D. An analysis of stress redistribution for different stages of the MD in simulated models provided a different characteristic of an irregular shaped ribs/snooks failure. Presence of moderate roof strata is found to be, relatively, more significant for the rib/snook design. Based on the simulation results, an attempt is made to provide a model for the rib/snook design in MDCSIR-CIMF

Toxins and Cancer Therapy
No full textCancer has been a patient-specific and difficult-to-treat disease for decades, resulting in more deaths since 1900 than all other diseases except cardiovascular diseases. As societies around the world continue to shift towards an aging population, the social and economic burden created by cancer will only rise in the coming decades, necessitating continued improvement in our cancer therapies. Remarkably, in the late 1800s, bone surgeon William Coley serendipitously discovered that bacteria could be administered to patients as an effective (and sometimes toxic) form of cancer therapy known as "Coley's Toxins". His discoveries unknowingly led to two fields of cancer therapy that have been in development for decades and are now leading to significant improvements in therapy for cancer patients: immune-based and toxin-based therapies for cancer. Articles included here discuss the discoveries that emerged from Coley's Toxins that enable us to harness the immune system and microbial toxins to combat cancers, as oncology shifts from a field dominated by chemotherapy for most of the 20th century to biologic therapies that will dominate the 21st century
Clinical Results and Functional Evaluation of the Chrisman-Snook Procedure for Lateral Ankle Instability in Athletes
No full textThere is no consensus regarding optimum surgical treatment for chronic ankle instability. The purpose of this study is to describe a variation of the Chrisman-Snook lateral ligament reconstruction that the senior author uses in patients with chronic ankle instability recalcitrant to conservative management. All patients who underwent reconstruction from 1997 to 2006 were identified, and those with a minimum 2-year follow-up were included, representing a total of 44 ankles in 43 patients. All underwent clinical evaluation and completion of the Foot and Ankle Outcome Survey and the Kaikkonen Scale. At mean follow-up of 4.4 years, mean dorsiflexion loss was 2° compared with the nonoperative side. The postoperative mean Foot and Ankle Outcome Survey score was 74 ± 16 (range, 36-98), while the mean Kaikkonen total score was 77 ± 14 (range, 40-95). Thirty-eight patients (84.6%) were satisfied with their result. Six patients (13.6%) underwent reoperation, including 4 with peroneal tendon scarring requiring tenolysis. Return to sport was achieved in 28 of 35 patients (80%) at a median of 6 months postoperatively. It is concluded that dorsiflexion loss can be minimized and return to sport expected in most patients following this variation of the Chrisman-Snook reconstruction.Levels of Evidence: Therapeutic, Level IV</jats:p
