![]() ![]() The precise mechanisms contributing to these motor symptoms in PD remain largely unknown. Mean (standard deviation) of the Pearson correlation coefficients between homologous temporal components and mean (standard deviation) of the normalized scalar products between weight coefficients are reported on both features of muscle synergies. Muscle synergy analysis may represent a new framework to examine the pathophysiological basis of specific motor symptoms in Parkinson’s disease (PD), including balance and gait disorders that are often unresponsive to treatment. Maximum muscle activities were compared using non- parametric analysis of variance. The Panel B shows primitive signals (on the left) and weight coefficients for homologous muscle synergies retained according to both criteria (the dark gray is for the eigenvalue > 1 and the light gray is for the eigenvalue > 0.5), and related to the fastest pace. Non-negative matrix factorization was used to compute muscle synergies. Through the statistical analysis, we found that Synergy 1 (which comprised about half of total variance accounted for all synergies) was highly correlated. ![]() The explained cumulative variance refers to the fastest walking speed. Mean numbers of synergies during level running at 2.5, 3.3, and 4.1 m/s were 4.1 0.6, 4.3 0.5, and 4.2 0.7, respectively, and those during uphill running at. On the top right, the explained cumulative variance (mean ± standard deviation errorbar) of five retained synergies is reported. Based on cumulative percentages of variance explained by each muscle synergy for each condition, three to five types of muscle synergy were identified across all subjects (Fig. For each limb (healthy in black, unaffected in dark gray, affected in light gray), bars represent the result achieved for all ordered walking speeds (i.e., 0.5, 0.7, 0.9, and 1.1 km/h). Synergies ensure that most of the variance is good. low pass filter cut-off had the effect of decreasing the variance accounted for by a set number of synergies and affected individual muscle contributions. The basis vectors of this low-dimensional subspace, termed muscle synergies, are hypothesized to reflect neurally-established functional muscle groupings. reduces the variance of the shape by using principal component analysis. On the top left, the percentage of subjects presenting different number of synergies, according to the criteria of the eigenvalue > 1 and the eigenvalue > 0.5, is reported. Good variance (V GOOD) does not affect the selected performance variable, while bad variance (V BAD) does. Evidence for muscle synergy during mastication is scarce, partly due to the.

It’s safe to say that the Resident Evil series is doing very well at this time. In reality, it’s a combination of all these factors and more. Narrowing their success down to a single element is difficult: one could cite their strong IP, in-house engine, monopoly over the survival horror genre, commitment to DLC, marketing, or attention to detail. At this time, it seems that the formula for a successful remake is to take a leaf out of Capcom’s book. From the freshly released Dead Space and the recently announced Silent Hill 2, to Pokémon BDSP and Final Fantasy VII – remakes are in fashion. Other developers are clearly taking inspiration and direction from Capcom’s approach to remakes. Kennedy – he keeps his dry sense of humour, but the developers take time to show how the events of RE2 affected him and his mental health. They removed the uncomfortable, outdated sexism, and they even took the care to retain the corny jokes cracked regularly by the game’s protagonist, Leon. ![]() The remake is almost universally praised for its attention to detail and faithful recreation, while simultaneously innovating new mechanics (such as parrying) and developing the classic characters into being more plausible, animated, and likeable. We can breathe a sigh of relief, because it appears that Capcom has struck gold again. But the principal question on many hardcore fans’ minds was one of concern: will Capcom get it right? ![]() When the remake was announced, it generated a lot of excitement and speculation. The original version was lauded as one of the greatest games of all time and still holds the top spot for many people, quoted as redefining videogames as a whole and building the foundation for modern gaming principles. The much anticipated RE4 Remake was released very recently, on 24 March 2023. This restored fans’ confidence in future titles, but there was still some lingering anxiety over the most popular entry in the series: Resident Evil 4.Ĭapcom has a wealth of classic series’ to remake, and a loyal playerbase who will eat up their new releases The developers seemed to have found a good middle ground between survival horror and action. There was no cut content, the duration was perfect, the setting and characters were memorable, and the gameplay was satisfying and balanced. It felt more like DLC than a separate game, and so the price point was not justified – especially compared to the quality of RE2R.Ĭapcom was able to recover from this wobble with the release of Resident Evil 8, a fantastic original entry in the series. Although the game looked fantastic in terms of graphics and character design, people were generally disappointed with its short length and cut content. The game has now sold over 10 million copies, outselling the original, and won ‘Ultimate Game of the Year’ at the 2019 Golden Joystick Awards.įans soon turned their attention to the Resident Evil 3 Remake, eagerly awaiting the return of the terrifying Nemesis enemy, rendered with updated technology for a greater fear-factor. Resident Evil 2 Remake brought the classic 1998 game to a modern audience with improved graphics and gameplay but the same tense atmosphere. In 2019, it appeared that Capcom had perfected the art of the remake. But Capcom regained its footing by distancing itself from action, and returning to its survival horror roots with the critically acclaimed Resident Evil 7 (my own personal favourite in the series). After Resident Evil 6, the series was floundering and declining in popularity. These games became available on Nintendo Swtich years after their initial release.Ĭapcom is set to launch Resident Evil 4 remake on March 24 for PC, PlayStation 4, PlayStation 5, and Xbox Series X|S.The Resident Evil series has had a resurgence in the last six or so years, despite the catastrophic failures of its Netflix adaptation and mediocre CGI films. It’s possible, however, that Resident Evil 4 remake becomes available on Nintendo Switch in the future with a cloud-only version like Resident Evil 2 remake and Resident Evil 3 remake did. Even PC users with recommended specs can experience FPS drops, according to Capcom, so it’s hard to imagine Resident Evil 4 remake properly working on Nintendo Switch. It’s currently unclear whether Capcom is planning to port the game to Nintendo Switch at a later date, but the answer is likely no, given the hardware limitations the Nintendo Switch has when it comes to supporting AAA titles. The only platforms the game will launch on are PC, PlayStation 4, PlayStation 5, and Xbox Series X|S. Unfortunately, Resident Evil 4 remake won’t launch for Nintendo Switch. Can you play Resident Evil 4 remake on Nintendo Switch? ![]() ![]() ![]() Currently, controversy exists in melanoma literature about whether to observe patients with clinical N0 disease or to perform an SLNB. Further questions arise about whether SLNB should be performed in all high-risk patients with clinically N0 SCC. Although lymph node dissection is recommended for patients with regional lymph node disease, no significant studies have determined whether this affects overall survival for patients with melanoma and nonmelanoma skin cancers. 6 An uncertainty to be explored is the next step in the treatment of patients with SCC and positive SLNB results. Some view this as a contraindication for performing SLNB, but the use of single-photon emission computed tomography and preoperative lymphoscintigraphy can substantially decrease this false-negative rate. Limitations to SLNB include false-negative rates, particularly high for tumors on the head and neck because of alternate draining routes and bifurcating anatomy. Given the cost and morbidity associated with prophylactic lymph node dissection, patients may benefit from a less invasive SLNB procedure before considering dissection. Overall, we found prophylactic lymph node dissection to be overused and SLNB is underused in high-risk SCC. 4 The SLNB positivity rate for stage 1B tumors is 7% to 10%, which is lower than that of high-risk SCC tumors. 3 The National Comprehensive Cancer Network guidelines recommend discussing and offering SLNB to patients with melanoma skin cancers of stages 1B and up. The reported positivity rate of SLNB in the setting of high-risk SCC in the literature is 12% to 44%. In a validation study by Schmitt et al, 2 tumors with 2 or 3 high-risk features had an SLNB positivity rate of 29%, whereas tumors with all 4 risk features had lymph node metastasis rate of 50%. T1 tumors have no high-risk features, whereas T2a tumors have 1, T2b have 2 to 3, and T3 have all 4 or bone invasion. This new staging system stratified T staging of SCC tumors based on the number of high-risk features present (>2-cm diameter, poor differentiation, perineural invasion, extension beyond subcutaneous fat). 1 Recent data have led to an updated staging system for cutaneous SCC proposed by Brigham and Women’s Hospital, which emphasizes the presence or absence of high-risk features. To date, the most important determinant of mortality in SCC is the presence of lymph node metastasis. With recent changes in staging of cutaneous squamous cell carcinoma (SSC), we examine the underuse of the sentinel lymph node biopsy (SLNB) in the management of high-risk SCC.
