The phrase "although some methods have" is correct and usable in written English.
It can be used to introduce a contrast or exception regarding the methods being discussed, typically in a more complex sentence structure.
Example: "Although some methods have proven effective, others have not yielded the desired results."
Alternatives: "even though some techniques have" or "while certain approaches have".
Although some methods have been developed to detect PDGF-BB, few can provide quantitative results using an affordable and portable device that is suitable for home use or field application.
Although some methods have been developed in the field of complex networks, only a few of them are concerning time-varying coupling strengths.
Although some methods have been already studied to obtain the variations of laser spot size with plasma distance such as SDE (source dependence expansion) [35, 36], but these methods present only the variation of laser spot size with distance.
These compounds may also be of therapeutic use because they have distinct functional and therapeutic profiles from "balanced agonists". Although some methods have been proposed to identify biased ligands, no comparison of these methods applied to the same set of data has been performed.
Although some methods have been assumed to be safe and easy to use, such as teething necklaces or quack remedies, they increase the risk of strangulation or aspiration of small beads [ 14].
So far, there is no general method for the morphometric analysis of all these types of symmetry, although some methods have been proposed for specific types [ 37, 38] and an application of the present methodology to one type of symmetry has been published [ 39].
Although not evaluated in this study, some methods have been developed to this aim, such as 'ComBat' [ 22] that proved effective on Infinium 27K and 450K data [ 21, 23].
Therefore, although some experimental methods have been launched to screen favourable drug combinations by disease-relevant phenotypic assays [ 8], the high-throughput identification of synergistic agent combinations arising from numerous agents remains an unresolved issue [ 9].
Although these methods have some advantages, however, all these techniques are suffering from some limitations such as high fabrication cost and process time.
Although GBS methods have some advantages for genome-wide SNP discovery and genotyping, especially for species for which a reference genome has not been established, they also have limitations, which include the requirements for complicated DNA library preparation procedures and intensive bioinformatics pipelines.
Although some of these methods have been performed well, they have not considered either some restrictions or a multi-objective function in their design.
