This paper reviews the NTIRE 2024 challenge on image super-resolution
($\times$4), highlighting the solutions proposed and the outcomes obtained. The
challenge involves generating corresponding ...high-resolution (HR) images,
magnified by a factor of four, from low-resolution (LR) inputs using prior
information. The LR images originate from bicubic downsampling degradation. The
aim of the challenge is to obtain designs/solutions with the most advanced SR
performance, with no constraints on computational resources (e.g., model size
and FLOPs) or training data. The track of this challenge assesses performance
with the PSNR metric on the DIV2K testing dataset. The competition attracted
199 registrants, with 20 teams submitting valid entries. This collective
endeavour not only pushes the boundaries of performance in single-image SR but
also offers a comprehensive overview of current trends in this field.
To evaluate the aesthetic outcome after application of rectangle periosteous flap to cover corrugator.
On the basis of regular rhytidectomy, a inter-eyebrow periosteous flap is applied to cover the ...fascia flap of corrugator by means of turnover. This manipulation helps to separate the skin from the muscle and prevent the re-adherence between the skin and muscle.
The approach was applied on 15 cases. The follow-up ranged from 6 months to 1 year. The results were satisfactory.
The method is effective in elimination of inter-eyebrow crease.
To investigate the efficacy and side effects of highly active antiretroviral therapy (HAART) in Chinese AIDS patients.
45 antiretroviral drug-naive AIDS patients were enrolled and divided into two ...groups by their baseline CD(4) count < 100/microl or > or = 100/microl. Clinical, virological and immunological outcomes as well as side effects were followed at baseline and at the end of month 1, 3, 6, 9, 12 after receiving HAART.
Among the 45 HIV/AIDS patients included, by the end of 12 months of HAART, the plasma viral load (VL) got a mean reduction by 2.8 lg copies/ml, CD(4) count had a mean gain of 187/microl, among which the naive phenotype increased by 68/microl and the memory phenotype by 119/microl. The CD(4)(+)CD(28)(+) T cell percentage went up from (62.5 +/- 25.8)% to (82.6 +/- 15.6)% (P < 0.001); and there was a significant reduction of CD(8)(+) T-cell activation. In the 31 patients with their baseline CD(4) count < 100/microl, 11 had a VL < 50 copies/ml, and 14 had fluctuations in their VL; while in 1
To probe the candidate susceptibility gene (s) of type 2 diabetes in the formal mapping region, 1p36.33-p36.23, in Han people of Northern China using single nucleotide polymorphisms (SNPs).
23 SNPs ...located in 10 candidate genes in the mapping region were chosen from public SNP domain by bioinformatic methods and single base extension (SBE) method were used to genotype the loci in 192 sporadic type 2 diabetes patients and 172 normal individuals to perform case-control study.
Among the 23 SNPs, 8 were found to be common in Chinese population. There were statistically different in the allele frequency of 2 SNP, rs436045 in the protein kinase C/xi gene and rs228648 in Urotensin II gene between case and control groups.
The two SNP may be associated with type 2 diabetes in Han people of China, which makes base for further study of the relation between the genes they located with type 2 diabetes.

To explore the method of treating serious secondary fronto-orbital fracture deformities through intro-extra cranial approach.
The fronto-orbital fracture was divided into two types according to ...whether there were any large scale fronto-orbital bone defects: type I: Large scale fronto-orbital bone defect; type II: Concave fronto-orbital fracture deformity without large scale bone defect. Both types were treated through intro-extra cranial approach to expose the fracture site. For type I deformity, the bone defects were repaired and reconstructed with outer table of cranial bone and artificial bone. For type II, the deformity was repaired by osteotomy, bone reposition and internal rigid fixation.
18 cases were treated from June 1998 to October 2000, include type I, 12 cases, and type II, 6 cases. All the patients recovered well and the post-operative appearance were greatly improved.
Intro-extra cranial approach can expose the fractured site better than the simple extrocranio approach, and make the operation mo
This paper presents a new method of individual prefabricated titanium implant for the reconstruction of the skull bone defect.
A computer-based 3D model of the cranial bone defect is created from ...helical CT-data and serves as the basis for the computer aided design and manufacturing (CAD/CAM) of the individual prefabricated titanium implant for the cranial bone defect reconstruction.
Since 2001, a total of nine patients suffering from the cranial bone defect have been operated on by this method with satisfied result. The fallow-up is 3 to 12 months.
These individual prefabricated titanium implants have won a high precision, a good biomechanics and a excellent biocompatibility. It is a quite ideal and very simple method with much less complication for the surgical treatment of the cranial bone defect.
